RESUMEN
Single crystals of the title salt, C21H21NH(+)·Cl(-), were isolated as a side product from the reaction involving [(C6H5CH2)3NH]2[HPO4] and Sn(CH3)3Cl in ethanol. Both the cation and the anion are situated on a threefold rotation axis. The central N atom in the cation has a slightly distorted tetra-hedral environment, with angles ranging from 107.7 to 111.16â (10)°. In the crystal, the tri-benzyl-ammonium cations and chloride anions are linked through N-Hâ¯Cl and C-Hâ¯Cl hydrogen bonds, leading to the formation of infinite chains along [001].

RESUMEN
In the title salt, [(CH3CH2CH2)2NH2]4[Sn(C2O4)4]·H2O, the Sn(IV) atom of the stannate anion is located on a special position with -42m symmetry.

In the crystal, the anions and cations are linked by N-Hâ¯O hydrogen bonds, forming a three-dimensional network. This network is futher stabilized by weak O-Hâ¯O hydrogen bonds involving the water mol-ecules and oxalate O atoms. The crystal studied was refined as an inversion twin.

RESUMEN
The title compound, [Sn(C6H5)2Cl2(CH4N2S)2], has been obtained from the reaction between Sn(C6H5)2Cl2 and SC(NH2)2. The asymmetric unit consists of one half of the mol-ecular unit, the remainder generated by a twofold rotation axis located along the Cl-Sn-Cl bonds. The Sn(IV) atom is coordinated by two phenyl groups, two Cl atoms and two thio-urea ligands in an all trans octa-hedral C2Cl2S2 environment. Individual mol-ecules are connected through N-Hâ¯Cl hydrogen bonds, leading to a three-dimensional network structure. Intra-molecular N-Hâ¯Cl hydrogen bonds are also present.
RESUMEN
The title salt, C14H16N+·C6H7AsNO3 -·H2O or [(C6H5CH2)2NH2][H2NC6H4As(OH)O2]·H2O, (I), was synthesized by mixing an aqueous solution of (4-amino-phenyl)-arsonic acid with an ethano-lic solution of di-benzyl-amine at room temperature. Compound I crystallizes in the monoclinic P21/c space group. The three components forming I are linked via N-Hâ¯O and O-Hâ¯O inter-molecular hydrogen bonds, resulting in the propagation of an infinite zigzag chain. Additional weak inter-actions between neighbouring chains, such as π-π and N-Hâ¯O contacts, involving phenyl rings, -NH2 and -As(OH)O3 functions, and H2O, respectively, lead to a three-dimensional network.
RESUMEN
The title SnIV complex, [Sn(C6H5)3Cl(C18H15O4P)], is a formal adduct between triphenyl phosphate (PhO)3P=O and the stannane derivative chlorido-tri-phenyl-tin, SnPh3Cl. The structure refinement reveals that this mol-ecule displays the largest Sn-O bond length for compounds including the X=OâSnPh3Cl fragment (X = P, S, C, or V), 2.6644â (17)â Å. However, an AIM topology analysis based on the wavefunction calculated from the refined X-ray structure shows the presence of a bond critical point (3,-1), lying on the inter-basin surface separating the coordinated phosphate O atom and the Sn atom. This study thus shows that an actual polar covalent bond is formed between (PhO)3P=O and SnPh3Cl moieties.
RESUMEN
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-Hâ¯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 0.525â (10):0.475â (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 0.725â (4):0.275â (4).
RESUMEN
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-Hâ¯O hydrogen bonds, leading to an infinite chain extending parallel to the b-axis direction. Neighbouring chains are linked by N-Hâ¯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 0.5342â (7):0.4658â (7).
RESUMEN
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-Hâ¯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-Hâ¯O hydrogen bonds, giving R(4) (4)(12) ring motifs, forming chains propagating along [010]. The chains are bridged by C-Hâ¯O inter-actions, forming a two-dimensional network lying parallel to (101).
RESUMEN

RESUMEN
The title salt, [(CH(3))(2)NH(2)][Sn(C(6)H(5))(3)Cl(2)], was obtained as a by-product of the reaction between bis-(dimethyl-ammonium) oxalate and triphenyl-tin chloride. In the stannate anion, the trigonal-bipyramidal coordination environment of the Sn(IV) atom is defined by the phenyl groups in equatorial and the Cl atoms in axial positions. The cations are connected to adjacent anions through N-Hâ¯Cl and C-Hâ¯Cl hydrogen-bonding inter-actions, leading to a chain motif parallel to [100].
RESUMEN
The title compound, (C(14)H(16)N)[Sn(C(6)H(5))(3)(C(2)O(2))], was synthesised by allowing C(2)O(4)(Bz(2)NH(2))(2) (Bz = benzyl) to react with SnPh(3)Cl. The asymmetric unit is built up by four SnPh(3)C(2)O(4) anions and four Bz(2)NH(2) cations which are related by a pseudo-inversion centre. Each Sn(IV) cation is five-coordinated by the three phenyl groups and two O atoms belonging to the chelating oxalate ligand; the coordination geometry is that of a distorted trigonal bipyramid. Anions and cations are linked through N-Hâ¯O hydrogen bonds into a layer structure parallel to (001). Moreover, the anion-cation pairs are associated by two bifurcated N-Hâ¯O hydrogen bonds, generating pseudo-dimers. One of the phenyl groups of one anion is disordered over two sets of sites in a 0.69:0.31 ratio. The Flack parameter value of 0.44â (1) indicates racemic twinning.
