摘      要：The cyano-bridged bimetallic complex K3(TMS)2(H2O)2Cr(CN)6 with three- dimensional microporous structure was synthesized and characterized. The title complex (C14H20CrK3N, Mr = 601.78) crystallizes in monoclinic, space group C2/c with a = 14.357(4), b = 9.331(3), c = 19.180(6) ?, β = 96.754(5)o, V = 2551.6(13) ?3, Z = 4, Dc = 1.567 g/m3, μ(MoKα) = 1.141 mm-1, F(000) = 1228, the final R = 0.0440 and wR = 0.0990 for 1760 observed reflections (I 2σ(I)). In the crystal, two [Cr(CN) ]3- units, four K+ ions and two oxygen atoms of two 6 TMS molecules are linked to form a sixteen-membered ring and an extended three-dimensional structure.
