摘要
A novel two-dimensional supramolecular complex [Mn（phen）（DPZDA）（H2O）]·2H2O has been synthesized by the reaction of Mn（CH3COO）2, 1,10-phenanthroline （phen） and H2DPZDA （3,5-dimethyl-pyrazine-2,6-dicarboxylic acid）. Elemental analysis, IR spectra and X-ray singlecrystal diffraction were carried out to determine the composition and crystal structure of the title complex. Crystal data： triclinic system, space group P1, a = 7.7474（13）, b = 9.3381（15）, c = 15.146（3） A, α = 93.872（3）, β= 102.451 （11 ）, y = 105.261 （ 11）°, C20H20MnN4O7, Mr = 483.34, Z = 2, F（000） = 498, V=1023.2（3）A^3, Dc=1.569 g/cm^3,μ=0.697 mm^-1, -9≤h≤9, -11≤k≤10, -18≤l≤12, R = 0.0365 and wR=0.0901 for 3585 independent reflections （Rint= 0.0165） and 2923 observed reflections （I〉 2σ（I））. Structural analysis indicates that Mn（Ⅱ） adopts a distorted octahedral geometry. The 2-D framework supramolecular structure of the title complex is constructed from hydrogen bonds and π…π interactions.
