摘 要:Four new Mn II coordination polymers,[Mn 1.5(tbip)(Htbip)(bib)].2H2O(1),[Mn 4(tbip) 4(bip)].2H2O(2),[Mn2(tbip)2(bbp)(H2O)](3),and [Mn3(tbip)3(bix)2](4)(H2tbip = 5-tert-butyl isophthalic acid;bib = 1,4-bis(imidazol)butane,bip = 1,3-bis(imidazol)propane,bbp = 1,3-bis(benziminazol)propane,bix = 1,4-bis(imidazol-1-ylmethyl)benzene) have been synthesized under hydrothermal conditions.1 exhibits a pcu topology containing [Mn3(COO)6] units.2 shows a 4-connected dia topology containing alternate mono/trinuclear Mn II units.3 features a 3D 8-connected net with a(36.4 16.5 6) topology showing [Mn4(COO)6(H2O)2] 2+ units.4 has a 3D 8-connected net hex topology containing [Mn3(COO) 4 ] 2+ ***,the magnetic properties of four complexes were investigated.
