Synthesis and structures of a triply-fused incomplete-cubane cluster [{(η⁵-C₅Me₅)WS₃}₃Cu₇(MeCN)₉](PF₆)₄ and a 2D polymer [(η⁵-C₅Me₅)WS₃Cu₃Cl(MeCN)(pz)]PF₆ (pz = pyrazine)

Abstract

The reaction of PPh₄[(η⁵-C₅Me₅)WS₃] with 3 equiv. of [Cu(MeCN)₄]PF₆ in MeCN yielded an unusual high nuclearity W/Cu/S cluster [{(η⁵-C₅Me₅)WS₃}₃Cu₇- (MeCN)₉](PF₆)₄ 1, which in turn gave rise to a 2D polymer [(η⁵-C₅Me₅)WS₃Cu₃Cl(MeCN)(pz)]PF₆ 2 upon treatment with pyrazine in MeCN in the presence of LiCl.
