摘要

Two coordination polymers with the formula of [M_2(DPA)_2(C_2O_4)(C_2O_4)]_(infinity) (M = Cu 1, Zn, 2; DPA = dipyridylamine) were synthesized under hydrothermal conditions. Both complexes are crystallized in triclinic system, space group P1 with the cell parameters: a = 8.3078(3) A, b = 9.1192(3) A, c = 9.2316(3) A, alpha = 115.164(1) deg, beta = 9.0862(1) deg, gamma = 103.559(1) deg, V = 603.17(4) A, Z = 2 for complex 1 and a = 8.5348(2) A, b = 9.0451(2) A, c = 9.0862(3) A, alpha = 114.305(1) deg, beta = 100.493(1) deg, gamma = 97.318(1) deg, V = 612.34(2) A, Z = 2 for complex 2, respectively. X-ray single-crystal structural determinations reveal that these two complexes are both composed of one-dimensional zigzag chains built up via the [M(DPA)]~(2+) fragments and alternately bridged bidentate mu_(1,3)-C_4O_4~(1-), tetradentate C_2O_4~(2-) ligands. The coordination environments of the M(II) centers adopts a slightly distorted trigonal bipyramid bonded with two N atoms of DPA, one O atom of squatate and two O atoms of oxalates. The intrachains N - H … O and C-H…O hydrogen bonds play an important role on the additional stabilization in constructing the open frameworks.
