配位聚合物Mn(2,4,6-TMBA)2(H2O)3n·2nH2O的水热合成和晶体结构

摘要

The title compound, [Mn(2,4,6-TMBA)2(H2O)3]n·2nH2O (1), where 2,4,6-TMBA=2,4,6-trimethylbenzoic acid, was synthesized and its crystal structure was determined by X-ray diffraction analysis. The crystal is of monoclinic, space group C2/c with a=2.929 9(6) nm, b=1.036 4(2) nm, c=8.222 04(17) nm, V=2.494 7(9) nm3, Z=rn4, M=471.40, Dc=1.255 g·cm-3,μ=0.571 mm-1, F(000)=996, Rint=0.029 4, R=0.037 6 and wR=O.094 9. The Mn atoms are octahedrally coordinated by two O atoms of two ligands and four O atoms of water. The carboxyl group coordinates to Mn(Ⅱ) in the mode of monodentate, while the O atoms of water molecules coordinates in bridging mode. The complex shows a one-dimensional chain structure bridged by water molecules.CCDC:297750.
