摘要
The solvothermal reaction of magnesium nitrate with bi-phenyl-4,4′- dicarboxylic acid in N,N-dimethyl-formamide and water leads to the formation of crystals of the title complex, [Mg(C14H8O4)(H2O)2] n. In the crystal structure, the Mg cations are coordinated by six O atoms from two water mol-ecules and four symmetry-related biphenyl-4,4′-dicarboxyl-ate anions within slightly distorted octa-hedra. The Mg cations are located on a center of inversion, the biphenyl-4,4′-dicarboxyl-ate anions around a twofold rotation axis and the water mol-ecule in a general position. The Mg cations are linked by the anions into a three-dimensional framework.
