Unexpected ligand substitutions in the cluster core {Re_6Se_8}:synthesis and structure of the novel cluster compound Cs_(11)(H_3O)[Re_6Se_4O_4Cl_6]_3 centre dot 4H_2O

摘要

The compound Cs_(11)(H_3O)[Re_6Se_4O_4Cl_6]_3 centre dot 4H_2O containing a novel cluster core {Re6Se_4O_4} with ordered ligands,where the 4 positions of one face of a Se_4O_4 cube are occupied exclusively by Se atoms and 4 O atoms lie in the opposite face was synthesized via the interaction of solid Re_6Se_8Br_2 with molten KOH.
