Poly[[μ2-(1Z,N′E)-2-(1,3-benzothia­zol-2-ylsulfan­yl)-N′-(2-oxidobenzyl­idene-κ2 O:O)acetohydrazidato-κ2 O,N′](pyridine-κN)copper(II)]

In the title compound, [Cu(C16H11N3O2S2)(C5H5N)]n, the CuII atom displays a square-pyramidal CuN2O3 coordination geometry with strong elongation in the vertex direction. The hydrazone mol­ecule is coordinated to the CuII atom in a tridentate manner in the enolic form, creating five- and six-membered chelate metallarings. The pyridine mol­ecule completes the square-planar base of the copper coordination environment. The crystal structure displays zigzag polymeric Cu—O—Cu chains along [001]. Several weak π–π inter­actions between benzothia­zole rings were found in the same direction [centroid–centroid distances = 3.7484 (16), 3.7483 (16), 3.6731 (17) and 3.7649 (17) Å]

[1-(2-Oxidobenzyl­idene)-4-phenyl­thio­semicarbazidato-κ3 O,N 1,S](pyridine-κN)copper(II)

In the structure of the title compound, [Cu(C14H11N3OS)(C5H5N)], the CuII atom exhibits a slightly distorted square-planar CuN2OS coordination polyhedron consisting of a phenyl O, an azomethine N and a thio­amide S atom from the tridentate thio­semicarbazonate dianion, and the N atom of a pyridine mol­ecule. The thio­semicarbazonate ligand exists in the thiol tautomeric form as an E isomer. Rotational disorder of the pyridine and phenyl rings in a 1:1 ratio of the respective components is observed. An extensive network of weak N—H⋯S, C—H⋯O, C—H⋯N and C—H⋯S hydrogen-bonding inter­actions consolidates the structure

cis-(Pyridin-2-ylcarbonimidodithioato-κ2S,S′)bis(triphenylphosphane-κP)palladium(II)

The title compound, [Pd(C6H4N2S2)(C18H15P)2], was obtained as a minor product from the reaction of trans-PdCl2(PPh3)2 with piperazine-1,4-dicarbothioic acid bis(pyridin-2-yl)amide. The PdII atom displays a slightly distorted square-planar PdP2S2 geometry with a bidentately coordinated pyridin-2-ylcarbonimidodithioate ligand and two triphenylphosphine molecules, coordinated in cis positions. The crystal structure features weak π–π [centroid–centroid distance =3.7327(15) Å] and C–H...π interactions and contains an almost spherically shaped void of 50.4 Å3 per unit cell
