A New 3-D Mn(II) Naphthoic Acid Complex [Mn(1,4-DNC)(DMA)]n (1,4-DNC = 1,4-Naphthalenedicarboxylate, DMA = Dimethylacetamide)

Abstract

A new 3-D Mn(II)-organic extended framework with a 1,4-naphthalenedicarboxylate ligand, [Mn(1,4-DNC)(DMA)]n (1), was obtained by the solvothermal reaction of MnCl2⋅4H2O and 1,4-naphthalenedicarboxylate (1,4-H2DNC) in dimethylacetamide organic solvents. Each Mn(II) atom is five-coordinated in a triagonal–bipyramidal coordination environment by four carboxylate O atoms from four different 1,4-DNC2– ligands and one O atom from a terminal DMA molecule. The neighboring Mn(II) atoms are doubly bridged by 1,4-DNC2– ligands to give a one-dimensional coordination polymeric chain [Mn(COO)2]n, and each chain is connected to four other different chains through µ4-kO1: kO2: kO3: kO4 1,4-DNC2– ligands to form a 3-D network of 1.
