Nickel(II) complexes of dithiocarbimates from sulfonamides: syntheses and crystal structures

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

The rigid organic linkersN-(4-bromophenylsulfonyl)dithiocarbimate(2−) andN-(4-iodophenylsulfonyl)dithiocarbimate(2−) crystallize with two potassium cations and two water molecules in their asymmetric units, forming the title coordination polymers, [K2(C7H4BrNO2S3)(H2O)2]nand [K2(C7H4INO2S3)(H2O)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-(phenyl-sulfon-yl)dithio-carbimato-κS,S']platinate(II) monohydrate

The asymmetric unit of the title compound, (C₂₄H₂₀P)₂[Pt(C₇H₅NO₂S₃)₂]·H₂O, consists of two tetra­phenyl­phospho­nium cations, two half bis­[N-(phenyl­sulfon­yl)dithio­carbim­ato]platinate(II) dianions and one water mol­ecule. 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 phenyl­sulfonyl­dithio­carbimate ligands, forming a slightly distorted square-planar configuration. Besides the electrostatic attraction between oppositely charged ions in the crystal packing, intra­molecular C—H⋯O and several inter­molecular C—H⋯O, C—H⋯N and O—H⋯O hydrogen-bonding inter­actions between the cations, anions and water mol­ecules are observed.

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

In the title salt, (C₂₄H₂₀P)₂[Pt(C₇H₃Cl₂NO₂S₃)₂], the Pt^II ion (site symmetry ) is coordinated by two S,S′-bidentate N-(2,5-dichloro­phenyl­sulfon­yl)dithio­carbimate ligands, resulting in a slightly distorted PtS₄ square-planar geometry. In the crystal, a C—H⋯O inter­action is observed, as well as electrostatic attraction between the oppositely charged ions.

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

The Ni atom in the title complex, (C₂₄H₂₀P)₂[Ni(C₉H₁₇NO₂S₃)₂], lies on a twofold axis within a square-planar geometry defined by four S atoms derived from two dithio­carbimate dianions, each forming a four-membered chelate ring. A small distortion, described by a deviation of the Ni^II atom by 0.083 (1) Å from 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.
