Crystal structure of a new mixed-metal coordin-ation polymer consisting of NiII piperidine-di-thio-carbamate and penta-nuclear CuI-I cluster units.

ABSTRACT: A new heterometallic CuI-NiII coordination polymer, poly[[tetra-?3-iodido-?2-iodido-bis-(?3-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.
