Synthesis, Structures Of Cyano-Bridged Bimetallic And Synthesis, Structures And Magnetic Properties Of Transition Metal-Citrate Coordination Compounds

I, II, III, IV, V were obtained by reactions of K4[W(CN)8] with MnCl2-4H2O, [Cu(dien)3]Cl3,[Co(en)3]Cl3,[Ni(dien)3]Cl3;[Mn(C12H8N)3]Cl2 respectively. The formula of I, II, III, IV, V are as follows:(I) [Mn(H2O)2]2[W(CN)8]4H2O(II) [Cu(dien)]2[W(CN)8]4H2O(III) [Ni(dien)(H2O)]2[W(CN)8](IV) [Co(en)3]4 [W(CN)8]3-2H2O(V) [Mn(C12H8N2)2]2[W(CN)8] Structures of K4[W(CN)8] and H8C6O7 following:VI, VII were obtained by reactions of C6H8O7 with Co(NO3)2-6H2O, MnCl2-4H2O respectively. The formula of VI, VII are as follows:(VI) [Co3(C6H5O7)2(H2O)8]-6H2O(VII) [Mn3(C6H5O7)2(H2O)8]-6H2OI, II, III, IV, V, VI, VII were characterized by elementary analysis, IR, and the structures of I, II, VI, VII are determined by X-ray single crystal diffraction.
