Five 1D to 3D Zn(II)/Mn(II)-CPs Based on Dicarboxyphenyl-terpyridine Ligand: Stepwise Adsorptivity and Magnetic Properties

Abstract

Five coordination polymers, {[Zn(dtp)]•H2O} (1), {[Zn(dtp)]•2CH3OH•NMP} (2), {[Mn2(dtp)2(H2O)4]•7(H2O)} (3), {[Mn(Hdtp)(Cl)]} (4) and {[Mn(dtp)(H2O)]•1.5H2O} (5) with different dimensional structures, have been solvothermally synthesized by utilizing H2dtp ligand (H2dtp = 4’-(3,-5dicarboxyphenyl)-2,2’:6’,2”-terpyridine). All complexes are characterized by single-crystal X-ray diffraction, element analysis, IR spectra, thermogravimetric analysis (TGA) and powder X-ray diffraction (PXRD). The Zn(II)-based complexes 1 and 2 display a 2D wavy layer structure and a 3D porous framework with 1D channel, respectively. Whereas the three Mn(II)-complexes 3-5 exhibit two 1D chains and one 2D layer, respectively. Complexes 1 and 2 reveal strong solid-state luminescence, complexes 3-5 display antiferromagnetic exchange. Meanwhile, an unusual stepwise adsorption for CO2 was also observed in 2.
