Reaction of solutions of [Cp*2Mo2P2S3] (1; Cp* = eta(5)-C5Me5) in CH2Cl2 with solutions of CuHal (Hal = Cl, Br, I) in CH3CN gave after slow diffusion the novel coordination polymers [Cp*2Mo2P2S3(CuCl)(4)] (2), [Cp*2Mo2P2S3(CuBr)(3)] (3) and [Cp*2Mo2P2S3(CuI)(3)] (4). The products were characterized by elemental analysis, P-31 magic angle spinning (MAS) NMR spectroscopy and single-crystal X-ray crystallography. The solid-state structures of 2 and 3 are composed of two-dimensional polymeric networks, whereas that of 4 contains parallel stacks of one-dimensional ribbons. In all cases the planar cyclo-P2S3 middle deck of the organometallic building block 1 provides one or two P atoms of the PS dumbbells along with the singly bridging sulfur atom as coordination sites for the various copper halide subunits. The assignment of P atoms follows from the correlation of P-31 MAS NMR spectra with X-ray crystallographic data. In all compounds the distribution of main group atoms in the cyclo-P2S3 middle deck is different from that previously found in the starting material 1. (C) 2011 Elsevier B.V. All rights reserved.
