Poly[diaqua-μ4-biphenyl-4,4′-dicarboxylato-magnesium(II)]

چکیده
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(C(14)H(8)O(4))(H(2)O)(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.

The crystal structure of the polymeric title complex, [Zn(C(14)H(8)O(4))](n), is composed of layers parallel to (110) formed by linking of Zn-carboxyl-ate chains with biphenyl units of the biphenyl-2,4'-dicarboxyl-ate (bpdc) ligands. The Zn(II) atom is five-coordinated in a distorted square-pyramidal geometry by five O atoms from four bpdc ligands. The dihedral angle between the benzene rings i...
