Novel cyanide-bridged three-dimensional coordination polymer derived from an octahedral rhenium cluster [Re6Te8(CN)(6)](4-): Synthesis and crystal structure of [{Mn(H2O)(2)(DMF)}(2)Re6Te8(CN)(6)]center dot 2H(2)O

摘要

The reaction of a water solution of K4Re6Te8(CN)(6) with a solution of Mn(NO3)(2) in 0.02M hydrochloric acid in the presence of DMF gave crystals of a cluster rhenium complex [{Mn(H2O)2(DMF)}(2)Re6Te8(CN)(6)].2H(2)O.. The structure of the compound was determined by single crystal X-ray diffraction (a = 12.6679(9) angstrom, b=17.4524(12)angstrom, c 9.7882(6)angstrom, beta= 105.570(6)degrees, V=2084.6(3)angstrom(3), Z=2, space group P2(1)/n, R = 0.0389). In the complex, the [Re6Te8(CN)(6)](4-) cluster anions are linked to Mn2+, cations by the cyanide bridges, the manganese cations being additionally coordinated by the DMF molecule and two water molecules. The neighboring clusters are joined by Re-C-N-Mn bridges into a three-dimensional framework possessing cavities filled with doubly disordered water molecules.
