Synthesis and Crystal Structure of a 3-Fold Interpenetrated Supramolecular Cluster Based on The Incomplete Cubane-Like Precursor [Et4N]2[WO(μ-S)3(CuNCS)3] and 4,4-Bipyridine

摘要

A cluster-based 3D polymer {[WO(μ-S)3Cu3(NCS)(4,4'-bipy)_(2.5)]·2.5(aniline))_n (1) was isolated by reactions of [Et4N]2[WO(μ-S)3(CuNCS)3] with bidentate nitrogen donor ligand 4,4'-bipy in an aniline solution. Compound 1 contains a 3-fold interpenetrated network in which each incomplete cubane-like [WO(μ-S)3Cu3] core acts as a tetrahedral four-connecting node to interconnect four other equivalent ones via single and double 4,4'-bipy bridges.
