Abstract

A new heterometallic CuI-NiII coordination polymer, poly[[tetra-μ3-iodido-μ2-iodido-bis-(μ3-piperidine-1-di-thio-carbamato)propio-nitrilepenta-copper(I)nickel(II)] chloro-form monosolvate], {[CuI5NiIII5(C6H10NS2)2(C3H5N)]·CHCl3} n , has been synthesized and structurally characterized. This coordination polymer consists of an NiII mononuclear unit of NiII(Pip-dtc)2 (Pip-dtc- is piperidine-1-di-thio-carbamate) and a penta-nuclear copper(I) cluster unit of Cu5I5(CH3CH2CN). The NiII ion, which lies on an inversion centre, is surrounded by four S atoms in a square-planar coordination geometry while all CuI ions have distorted tetra-hedral coordination geometries. In the penta-nuclear copper(I) cluster unit, a mirror plane passes through one CuI ion and three I ions. All the S atoms in NiII(Pip-dtc) are also coordinated by the CuI ions, forming an infinite zigzag chain structure along the b-axis direction. The chains are weakly connected by solvent CHCl3 mol-ecules via Cl⋯I [3.653 (1) Å] and Cl⋯S [3.4370 (1) Å] short-contact inter-actions.
