摘要: Abstract. The 3D cobalt(II) coordination polymers [Co1.5(HDDB)(1,4-bib)1.5(H2O)]n (1), and {[Co2(DDB)(1,3-bib)2(μ2-H2O)]·H2O}n (2) were assembled by mixed-ligand synthetic strategy [H4DDB = 1,3-bis(2,4-dicarboxyphenyl) benzene, 1,3-bib 1,3-bis(1H-imidazol-4-yl)benzene, 1,4-bib 1,4-bis(1H-imidazol-4-yl)benzene]. Their structures determined single-crystal X-ray diffraction analyses further characterized elemental (EA), IR spectroscopy, powder (PXRD), thermogravimetric (TG) analyses. Single analysis reveals that complex 1 is an interestingly (3,3.6)-connected (63)4(65·88·102) net, 2 unprecedented dinuclear [Co2(COO)(μ2-H2O)] SBUs based (3,6)-connected (3·6·7)(32·43·54·63·7·82) net. Additionally, the magnetic properties of investigated.
