Abstract
The reaction of Cs4[Re6Te8(CN)6]×2H2O with Cu(en)2Cl2 in water affords crystals of a cluster complex [{Cu(H2O)(en)2}{Cu(en)2}Re6Te8(CN)6]×3H2O. The structure of the compound is determined by single crystal X-ray diffraction (a = 10.8082(4) Å, b = 16.5404(6) Å, c = 24.6480(7) Å, β = 92.696(1)°, V = 4401.5(3) Å3, Z = 4, space group P21/n, R1 = 0.0331, wR2 (all data) = 0.0652). In the complex, cluster [Re6Te8(CN)6]4–anions are linked by Cu2+ cations into zigzag chains through cyanide bridges. The coordination environment of the copper cations is complemented by ethylenediamine molecules. Each of the cluster anions is additionally coordinated by a terminal fragment {Cu(H2O)(en)2}.
