Synthesis and Crystal Structure of a 2D Honeycomb-like Polymeric Cluster (Et4N)3{[MoS4Cu2(μ-CN)]2(μ′-CN)}·2MeCN

Reaction of a preformed cluster (Et4N)2[MoS4(CuCN)2]·H2O (1) with acetic acid in MeCN gave rise to an interesting 2D polymeric cluster (Et4N)3{[MoS4Cu2(μ-CN)]2(μ′-CN)}·2MeCN (2). Compound 2 was characterized by elemental analysis, IR spectrum, and single crystal X-ray crystallography. In the structure of 2, the cluster core MoS4Cu2 of the cluster precursor 1 is retained and serves as a 3-connecting node to link equivalent nodes via single cyanide bridges, forming an anionic 2D (6,3) (honeycomb-like) network. The acetic acid induced aggregation of supramolecular compound 2 from the cluster precursor 1 suggests that this simple synthetic strategy be likely applicable to many related systems.
