Poly[di-µ-aqua-[µ6-N-(4-bromophenylsulfonyl)dithiocarbimato]dipotassium] and poly[di-µ-aqua-[µ4-N-(4-iodophenylsulfonyl)dithiocarbimato]dipotassium].

The rigid organic linkers N-(4-bromophenylsulfonyl)dithiocarbimate(2-) and N-(4-iodophenylsulfonyl)dithiocarbimate(2-) crystallize with two potassium cations and two water molecules in their asymmetric units, forming the title coordination polymers, [K(2)(C(7)H(4)BrNO(2)S(3))(H(2)O)(2)](n) and [K(2)(C(7)H(4)INO(2)S(3))(H(2)O)(2)](n). The anions and the water molecules link the potassium cations into broad two-dimensional networks, which are further linked by K···halide interactions.

Bis(tetra-phenyl-phospho-nium) bis-[N-(trifluoro-methyl-sulfon-yl)dithio-carbimato(2-)-κS,S']zincate(II).

The title salt, (C(24)H(20)P)(2)[Zn(C(2)F(3)NO(2)S(3))(2)], consists of a complex dianion and two tetra-phenyl-phospho-nium cations. The Zn(II) ion displays a distorted tetra-hedral coordination environment with four S atoms from two S,S'-chelated N-(trifluoro-methyl-sulfonyl-)dithio-carbimate anions. In the crystal, besides the ionic inter-action of the oppositely charged ions, inter-molecular C-H⋯O inter-actions between cations and anions are observed. One of the cations inter-acts with an inversion-related equivalent by π-π stacking between phenyl rings, with a centroid-centroid distance of 3.932 (4) Å.

Bis(tetra-phenyl-phospho-nium) bis-[N-(2,5-dichloro-phenyl-sulfon-yl)dithio-carbimato(2-)-κS,S']platinate(II).

In the title salt, (C(24)H(20)P)(2)[Pt(C(7)H(3)Cl(2)NO(2)S(3))(2)], the Pt(II) ion (site symmetry ) is coordinated by two S,S'-bidentate N-(2,5-dichloro-phenyl-sulfon-yl)dithio-carbimate ligands, resulting in a slightly distorted PtS(4) square-planar geometry. In the crystal, a C-H⋯O inter-action is observed, as well as electrostatic attraction between the oppositely charged ions.

Bis(tetra-phenyl-phospho-nium) bis-[N-(phenyl-sulfon-yl)dithio-carbimato-κS,S']platinate(II) monohydrate.

The asymmetric unit of the title compound, (C(24)H(20)P)(2)[Pt(C(7)H(5)NO(2)S(3))(2)]·H(2)O, consists of two tetra-phenyl-phospho-nium cations, two half bis-[N-(phenyl-sulfon-yl)dithio-carbim-ato]platinate(II) dianions and one water mol-ecule. The anions are completed by crystallographic inversion symmetry associated with the central Pt(II) ion. The Pt(II) ion is doubly S,S'-chelated by two symmetry-related phenyl-sulfonyl-dithio-carbimate ligands, forming a slightly distorted square-planar configuration. Besides the electrostatic attraction between oppositely charged ions in the crystal packing, intra-molecular C-H⋯O and several inter-molecular C-H⋯O, C-H⋯N and O-H⋯O hydrogen-bonding inter-actions between the cations, anions and water mol-ecules are observed.

Syntheses, crystal structure, spectroscopic characterization and antifungal activity of new N-R-sulfonyldithiocarbimate metal complexes.

Five new compounds with the general formula of (Bu(4)N)(2)[M(RSO(2)NCS(2))(2)], where Bu(4)N=tetrabutylammonium cation, (M=Ni, R=4-FC(6)H(4)) (1), (M=Zn, R=4-FC(6)H(4), 4-ClC(6)H(4), 4-BrC(6)H(4), 4-IC(6)H(4)), (2), (3), (4) and (5), respectively, were obtained by the reaction of the appropriate potassium N-R-sulfonyldithiocarbimate (RSO(2)N=CS(2)K(2)) with nickel(II) chloride hexahydrate or zinc(II) acetate dihydrate in metanol:water 1:1. The elemental analyses and the IR data are consistent with the formation of the expected bis(dithiocarbimato)metal(II) complexes. The (1)H and (13)C NMR spectra showed the signals for the tetrabutylammonium cation and the dithiocarbimate moieties. The compounds 1, 2 and 5 were also characterized by X-ray diffraction techniques. The nickel(II) is coordinated by two N-4-fluorophenylsulphonyldithiocarbimato(2-) ligands forming a planar coordination. The zinc(II) exhibits distorted tetrahedral configuration in compounds 2 and 5 due to the chelation effect of two sulfur atoms of the N-R-sulfonyldithiocarbimate ligands. The antifungal activities of the compounds were tested in vitro against Colletotrichum gloeosporioides, an important fungus that causes the plant disease known as anthracnose in fruit trees. All the complexes were active.

Bis(tetra-phenyl-phospho-nium) tris-[N-(methyl-sulfon-yl)dithio-carbimato(2-)-κS,S']stannate(IV).

In the title complex, (C(24)H(20)P)(2)[Sn(C(2)H(3)NO(2)S(3))(3)], the Sn(IV) atom is coordinated by three N-(methyl-sulfon-yl)dithio-carbimate bidentate ligands through the anionic S atoms in a slightly distorted octa-hedral coordination geometry. There is one half-mol-ecule in the asymmetric unit; the complex is located on a crystallographic twofold rotation axis passing through the cation and bis-ecting one of the (non-symmetric) ligands, which appears thus disordered over two sites of equal occupancy. In the crystal structure, weak inter-molecular C-H⋯O and C-H⋯S inter-actions contribute to the packing stabilization.

Bis(tetra-phenyl-phospho-nium) bis-[N-(octyl-sulfon-yl)dithio-carbimato(2-)-κS,S']-nickelate(II).

The Ni atom in the title complex, (C(24)H(20)P)(2)[Ni(C(9)H(17)NO(2)S(3))(2)], lies on a twofold axis within a square-planar geometry defined by four S atoms derived from two dithio-carbimate dianions, each forming a four-membered chelate ring. A small distortion, described by a deviation of the Ni(II) atom by 0.083 (1) Šfrom the plane through the four S atoms, and also by the torsion angles about the Ni-S bonds, implies a folded conformation for the chelate ring.
