Synthesis and structures of new octahedral water-soluble heterometal rhenium-molybdenum clusters

摘要

The interaction of polymeric Re3MoS4Te4 with molten KCN at 850 degreesC results in,rearrangement of the tetrahedral {Re3MoS4} cluster core to an,octahedral one, {Re6-xMoxS8}, and formation of two new molecular octahedral heterometal rhenium-molybdenum thiocyanide cluster complexes, [Re5MoS8(CN)(6)](5-) and [Re4Mo2S8(CN)(6)](5-), co-existing in the crystals Cs-5[Re4.5Mo1.5(mu(3)-S)(8)(CN)(6)].2H(2)O. The EDAX analyses and magnetic measurements data confirm them, presence of a mixture of cluster anions with x = 1 and 2. (C) 2003 Elsevier Ltd. All rights reserved.
