Acetonyltriphenyl-phospho-nium nitrate.

Crystals of the title salt, C(21)H(20)OP(+)·NO(3) (-), are composed of acetonyltriphenyl-phospho-nium cations and nitrate anions that mainly inter-act through electrostatic forces. The P atom in the cation has a slightly distorted tetra-hedral environment, with C-P-C angles ranging from 104.79 (7) to 112.59 (6)°. The sum of O-N-O angles of the nitrate anion is 359.99°, reflecting its trigonal-planar character. C-H⋯O hydrogen bonds help to consolidate the crystal packing.

Tetra-butyl-ammonium butyl-tetra-chlorido-stannate(IV).

In the title compound, [N(C4H9)4][Sn(C4H9)Cl4], the Sn(IV) atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetra-butyl-ammonium cation are partially disordered, each with refined site occupancies of 0.691 (6):0.309 (6). Weak C-H⋯Cl hydrogen-bonding inter-actions help to consolidate the crystal packing, as well as a short Cl⋯Cl inter-action of 3.295 (2) Å.

Poly[tetra-butyl-ammonium [chlorido-hexa-methyl-µ3-sulfato-distannate(IV)]].

In the structure of the title coordination polymer, {(C16H36N)[Sn2(CH3)6Cl(SO4)]} n , the two independent Sn(IV) atoms are coordinated in a trigonal-bipyramidal manner by three methyl groups in the equatorial plane and in the axial positions by either two O atoms of bridging SO4 (2-) anions or by a Cl atom and one O atom of a bridging SO4 (2-) anion, respectively. The [Sn2(CH3)6Cl(SO4)](-) anion forms an infinite zigzag chain parallel to the c axis. The cations are situated between these chains. Two of the four butyl groups of the cation are partially disordered over two sets of sites with site occupancies of 0.79 (2):0.21 (2) and 0.75 (2):0.25 (2), respectively. Weak C-H⋯O hydrogen-bonding inter-actions help to consolidate the crystal packing.

Poly[dibutyl-ammonium [nonamethylbis-(µ(3)-sulfato-κ(3)O:O':O'')tristannate(IV)]].

In the structure of the title coordination polymer, {(C(8)H(20)N)[Sn(3)(CH(3))(9)(SO(4))(2)]}(n), each of the three Sn(IV) atoms is coordinated in a trigonal-bipyramidal manner by three methyl groups in the equatorial plane and by two O atoms of SO(4) (2-) anions in the axial positions. The µ(3)-bridging mode of the sulfate anions leads to the formation of corrugated anionic layers parallel to (100). The uncoordinating O atom of one of the two SO(4) (2-) anions is N-H⋯O hydrogen-bonded to the dibutyl-ammonium cation inter-connecting the anionic sheets. The structure is partially disordered. The dibutyl ammonium ion is found on two positions with an occupancy ratio of 0.525 (10):0.475 (10), and one sulfate group with three connecting trimethyl stannyl groups is also positionally disordered over two sets of sites with an occupancy ratio of 0.725 (4):0.275 (4).

Dibutyl-ammonium bis-(hydrogen methylphosphonato-κO)triphenylstannate(IV).

The asymmetric unit of the title organotin salt, (C(8)H(20)N)[Sn(C(6)H(5))(3)(CH(4)O(3)P)(2)], contains two dibutyl-ammonium cations and two stannate(IV) anions consisting each of two monodentately bonding methyl hydrogenphosphate groups attached to an Sn(C(6)H(5)) unit. The overall coordination environment of the two Sn(IV) atoms is trigonal-bipyramidal defined by three phenyl C atoms in equatorial positions and two methyl hydrogenphosphate O atoms at the apical sites. In the crystal, the stannate(IV) anions are linked to each other via pairs of short O-H⋯O hydrogen bonds, leading to an infinite chain extending parallel to the b-axis direction. Neighbouring chains are linked by N-H⋯O hydrogen bonds involving the butyl-ammonium cations, giving a two-dimensional structure parallel to the ab plane. The crystal under investigation was found to be twinned by reticular merohedry with twin fractions of 0.5342 (7):0.4658 (7).

Dicyclo-hexyl-ammonium hydrogen phenyl-phospho-nate.

In the title salt, [(C(6)H(11))(2)NH(2)](+)·[C(6)H(5)PO(2)(OH)](-), the anion is monodeprotonated and acts as both a hydrogen-bond donor and acceptor. The anions are linked by pairs of O-H⋯O inter-actions, forming inversion dimers with R(2) (2)(8) ring motifs. These dimers are bridged by two dicyclo-hexyl-aminium cations via pairs of N-H⋯O hydrogen bonds, giving R(4) (4)(12) ring motifs, forming chains propagating along [010]. The chains are bridged by C-H⋯O inter-actions, forming a two-dimensional network lying parallel to (101).

Regular crystals of the title compound, (C(2)H(8)N)(2)[Sn(CH(3))(2)Cl(4)], were obtained by reacting SnMe(2)Cl(2) with (CH(3))(2)NH·HCl in ethanol in a 1:1 ratio. The Sn atom lies on a center of symmetry and is six-coordinated. It has a distorted octahedral SnC(2)Cl(4) environment with the Cl atoms in cis positions. The Cl atoms are connected to dimethyl-ammonium cations through N-H⋯Cl hydrogen bonds, forming an infinite chain extending parallel to [010].

In the crystal, neighbouring polymer chains are linked via C-H⋯π inter-actions, forming a two-dimensional network lying parallel to (001).

Dicyclo-hexyl-ammonium trimethyl-bis-(hydrogen phenyl-phospho-nato)stannate(IV).

In the title compound, (C(12)H(24)N)[Sn(CH(3))(3)(C(6)H(6)O(3)P)(2)], the SnMe(3) residues are axially coordinated by two monodentate [PhPO(3)H](-) anions, leading to a trigonal-bipyramidal geometry for the Sn(IV) atom. The two [SnMe(3)(PhPO(3)H)(2)](-) anions in the unit cell are associated into infinite chains along the a axis by O-H⋯O hydrogen bonds involving the hy-droxy group of the hydrogen phenyl-phospho-nate ion. The chains inter-act with one another via O-H⋯O hydrogen bonds along the c axis. These networks of anions assemble with the dicyclo-hexyl-ammonium ion through N-H⋯O hydrogen bonds, forming a three-dimensional network.

A new organic-inorganic compound, ethyl-enedi-ammonium hexa-chlorido-stannate(IV) p-anisaldehyde disolvate.

The asymmetric unit of the title organic-inorganic hybrid complex [systematic name: ethane-1,2-diaminium hexa-chlorido-stannate(IV)-4-meth-oxy-benz-alde-hyde (1/2)], (C2H10N2)[SnCl6]·2C8H8O2, contains one half of an ethyl-enedi-ammonium cation, one half of an [SnCl6]2- anion and one p-anisaldehyde mol-ecule. Both the organic cation and the quasi-regular octa-hedral inorganic anion are located about inversion centres. The organic cations and [SnCl6]2- anions lie in layers parallel to the ac plane with p-anisaldehyde mol-ecules occupying the space between the layers. A network of classical N-H⋯Cl and N-H⋯O hydrogen bonds exists between the ethyl-enedi-ammonium cations and the [SnCl6]2- anions and p-anisaldehyde mol-ecules. These inter-actions, together with non-classical C-H⋯O inter-actions between the ethyl-enedi-ammonium cations and the p-anisaldehyde mol-ecules, serve to hold the structure together. The crystal studied was refined as a two-component twin.

(3E)-4-[(Naphthalen-1-yl)amino]-pent-3-en-2-one hemihydrate.

The title compound, C15H15NO·0.5H2O, was prepared from α-naphthyl-amine and 2,4-penta-nedione in a 1:1 ratio.

The water mol-ecule interacts with two symmetry-related N-naphthyl-pent-3-en-2-one mol-ecules viaby O-H⋯O hydrogen bonds.
