| 摘 要： | 采用水热合成方法得到3个新的双肼桥连过渡金属化合物：[M（N2H4）2Cl2]n（M=Mn（1），Ni（2）），{[Co1.5（N2H4）3PO4（H2O）]·H2O}n（3），用单晶X射线衍射方法对其晶体结构进行表征。化合物1是以2个肼分子桥联金属Mn和Ni形成1D链状结构，而粉末XRD显示1与2是同构的。化合物3是以2个肼分子桥联金属Co形成1D链，不同的1D链再通过磷酸根PO43-进一步堆积形成3D结构。磁性测试表明肼桥在磁性中心之间传递反铁磁耦合作用。

| Abstract: | By employing the hydrothermal method, we have synthesized three transition metal compounds with double hydrazine (N2H4) as bridge:[M(N2H4)2Cl2]n(M=Mn(1), Ni(2)), {[Co1.5(N2H4)3PO4(H2O)]·H2O}n(3). Single-crystal X-ray diffraction reveals that the compound 1 are one-dimensional (1D) chains with two hydrazine molecules as bridge ligands. And powder X-ray diffraction analysis reveals that compounds 1 and 2 are isomorphous. The compound 3 first form 1D chains through two hydrazine molecules as bridge ligands and the PO43- connect the chains into a 3D extended structure. The magnetic measurement reveals the hydrazine as bridge ligand can mediate the antiferromagnetic (AF) coupling interaction between magnetic centers. |
