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 single- crystal 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), γ = 105.261(11)°, C20H20MnN4O7, Mr = 483.34, Z = 2, F(000) = 498, V = 1023.2(3) ·3, Dc = 1.569 g/cm3, 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 octa- hedral geometry. The 2-D framework supramolecular structure of the title complex is constructed from hydrogen bonds and π···π interactions.
