New types of complexes based on Re-4 chalcocyanide clusters - Syntheses and crystal structures of [Ni(NH3)(5)](2)[Re4Te4(CN)(12)]center dot 3.4H(2)O and [Cd(NH3)(5)][Cd(NH3)(3)][Re4Te4(CN)(12)]center dot 4H(2)O

Two new tetrahedral rhenium chalcocyanide cluster compounds [Ni(NH3)(5)](2) [Re4Te4(CN)(12)].3.4H(2)O (1) and [Cd(NH3)(5)][Cd(NH3)(3)][Re4Te4(CN)(12)]. 4H(2)O (2), exhibiting molecular (1) and chain-like polymeric structures ( 2), have been synthesized by treatment of the salt-like cluster compound K4 Re4Te4(CN)(12). 5H(2)O with solutions of nickel acetate and cadmium sulfate , respectively, in aqueous ammonia. Both compounds have been characterized by single-crystal X-ray diffraction analysis. Compound 1 crystallizes in th e monoclinic space group P2(1)/c [a = 19.572(3), b = 14,849(2), c = 23.576( 3) Angstrom, beta 145.97(1)degrees, Z = 4, V = 3834.4(9) Angstrom (3)], whi le compound 2 crystallizes in the triclinic space group P (1) over bar [a = 12.726(2), b = 13.408(2), c = 13,918(2) Angstrom, alpha = 111,31 (2), beta = 116.77(2), gamma = 90.17(2)degrees, Z = 2, V = 1935,3(5) Angstrom (3)].
