A novel two-dimensional supramolecular complex [Mn(phen)(DPZDA)(H_2O)]·2H_2Ohas been synthesized by the reaction of Mn(CH_3COO)_2, 1,10-phenanthroline (phen) and H_2DPZDA (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 P-1, a = 7.7474(13), b = 9.3381(15), c =15.146(3)(A), α = 93.872(3), β = 102.451(11), γ = 105.261(11)°, C_(20)H_(20)MnN_4O_7, Mr = 483.34, Z = 2,F(000) = 498, V = 1023.2(3)(A)3, D_c = 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. |
