Abstract

Crystal structures of Cs4[Re6Te8(CN)6]·2H2O (1) and Ba2[Re6Te8(CN)6]· 12H2O (2) are determined. Crystals 1 are orthorhombic, a = 14,282(1), b = 12.910(1), c = 18.040(1) Å, Vcell = 3326.3(8) Å3, space group Pbcn, Z = 4, dcalc = 5.715 g/cm3, R(F) = 0.0482 for 3193 Fhkl > 4σ(F). Crystals 2 are triclinic, a = 9.671(3), b = 9.697(4), c = 11.039(4) Å, α = 89.86(3), β = 72.34(3), γ = 82.46(3)∘, Vcell = 977.2(6) Å3, space group P1, Z = 1, dcalc = 4.733 g/cm3, R(F) = 0.0490 for 3226 Fhkl > 4σ(F). In both structures, the [Re6Te8(CN)6]4− anions form a distorted primitive cubic packing with distances between the centers 9.02-9.63 Å in 1 and 9.70-11.04 Å in 2. The Cs+ cations in 1 lie near the face centers of the cubes formed by the onions. In 2, cation pairs (Ba2+)2 bonded to two solvate water molecules are formed; the pairs lie at the centers of the anion cubes. In structures 1 and 2, there are shortened contacts between the tellurium atoms belonging to the neighboring anions (3.75-4.09 and 3.95-4.22 Å, respectively).
