    摘要: Two new complexes [Co(bipym)(dca)](dca) (1) and [Co(bipym)(dca)]2(ClO4)2 (CH3OH)×2H2O (2) (dca = dicyanamide, bipym = 2,2'-bipyrimidine) have been synthesized and their structuresl magnetically characterized. Complex 1 crystallizes in a monoclinic system P21/n space group, Z = 4, with a = 9.3710(2), b = 15.0690(3), c = 9.8920(2) A, β = 92.4780(10)°. Complex 2 crystallizes in a monoclinic system C2/c space group, Z = 4, with a = 16.4190(3), b = 17.0880(3), c = 12.1130(2) A, and β = 95.1070 (10)°. The crystal structure in 1 and 2 is a three-dimensional network contraction through the bridging 1,5-dca and bipym ligands. Temperature dependence of magnetic measurements show antiferromagnetic couplings in all cases with J = -7.22 for 1, and -7.11 cm-1 for 2, respectively.
