New Rhenium Octahedral Cluster Sulfido-cyanide Chain Polymer:The Synthesis and Crystal Structure of Cs_4[{Re_6S_8}(CN)_4S_(2/2)]

摘要

The chemistry of rhenium octahedral cluster chalco-genides demonstrates a rich diversity of types of chain-like,layered and framework structures as well as bridging ligands between clusters.The clusters can be connected via mu_3 inner ligands of cluster units, apical halogenide ligands, complex telluride Te_6 or Te_7 and halogen-telluride Te_8Q_(18)~(2-)groups,Q=Cl,Br~3,chalcogenides,dichalcogenide and trichalco-genide ligands.The latter family described by Prof.W.Bronger (so called "Bronger phases")seems to be most numerous and complete family of polymeric rhenium octahedral cluster chalcogenides with various bridges and connectivity between clusters.For example,Li_4Re_6S_(11) contains Re_6S_8 cluster units connected by six bridging m_2 sulfido ligands that gave Li_4[{Re_6S_8~i}(S)a~ frame- work according to Schafer notation.
