摘要：
Four heteronuclear complexes, [Ln2Co2L10(H2O)(phen)2] n(H2O) (Ln = La 1, n = 2; Ln = Nd 2, Sm 3, Gd 4, n = 0; HL = -methylacrylic acid, phen = 1,10-phenanthroline), have been synthesized and characterized by elemental analysis, IR and X-ray diffraction. The complexes with a discrete Co-Ln-Ln-Co tetranuclear molecule are isomorphous in the triclinic space group P1 and Z = 1, in which all metal ions are bridged by bidentate -methylacrylato groups. Magnetic measurements of 1, 2 and 3 show antiferromagnetic exchange interaction between paramagnetic centers.
