摘要

Abstract—

Solvothermal reactions of the flexible multicarboxylate ligand methylenebis(thioglycolic acid) (H2mbta) with Mn/Zn salts in the presence of 1,4-bis(1-imidazoly)benzene (bib) and 3, 5-bis(1-imidazoly)pyridine (bip) afforded two novel 2D layer coordination polymers [Mn(mbta)(bib)]n (I) and {[Zn(mbta)(bip)](H2O)}n (II) (CCDC nos. 2404028 (I), 2404045 (II)). The 2D layer structure of I features dinuclear manganese(II) unit joined by a pair of H2mbta ligands, whereas the 2D layer of II manifests that the flexible multicarboxylate H2mbta ligand directly bridges mononuclear zinc(II) unit. Furthermore, powder X-ray diffraction analysis, thermal degeneration, magnetic property of complex I and luminescence property of complex II are also investigated.
