| Abstract: | The reactions of aqueous solutions of the tetranuclear chalcocyanide cluster anions Re4Q4(CN)12]4–, where Q = S, Se, or Te, with an ammonia solution of copper(ii) chloride at room temperature afforded a series of polymeric cyano-bridged compounds {Cu(NH3)3}2{Re4Q4(CN)12}]·nH2O (Q = S (1), Se (2)) and {Cu(NH3)3}1.7{Cu(NH3)4}0.3Re4Te4(CN)12] (3) having chain structures. The structures of the compounds were established by X-ray diffraction analysis. Compounds 1 and 2 are isostructural and have ordered structures. In structurally similar compound 3, the copper atoms are disordered over two positions in such a way that the structure contains the bridging {Cu(NH3)3} fragments along with the terminal {Cu(NH3)4} fragments. |
