The use of cyano group of a transition-metal cluster complex to bond to another transition-metal complex has been realized in the syntheses of [{(Cu(en)2})2Re4(CN)12] ·5H2O (1) and [{(Cu(en)2})2Re6Te8 (CN)6]·5H2O (2), (en = ethylenediamine. These compounds have been synthesized by the reaction of an aqueous solurion of K4[Re4Te4(CN)12] ·5H2O (for 1) or K4[Re6Te8(CN)6] (for 2) with an ammonia solution of Cu(en)2Cl2. In each compound, two Cu(en)2 groups are bonded to the Re cluster through Cu-N(cyanide) bonds. In compound 1, which contains a tetrahedral cluster core, the Cu(en)2 groups are necessarily bonded to cis cyano groups; in compound 2, which has an octahedral cluster core, they are bonded to trans cyano groups. Compound 1 crystallizes inthe monoclonic space group C2/c with four formulas in unit cells of dimensions a = 18.9077(10), b = 15.4841(8), c = 14.4483(8) Å, β = 95.124(1)°, and V = 4213.1(4) Å3 (T = 153 K); compound 2 crystallizes in the triclinic space group P1̄ with one formula in a unit cell of dimensions a = 9.4906(3), b = 10.6529(4), c = 12. 6252(5) Å, α = 113.599(1)°, β = 103.404(1)°, γ = 92.659(1)°, and V = 1123.87(7) Å3 (T = 153 K).
