The title complex, [Mn(DPPZ)(PZDC)(H2O)] 1 (DPPZ = dipyrido[3,2 -a:2’,3’- c]phenazine and H2PZDC = pyrazine-2,3-dicarboxylic acid), has been hydrothermally synthesized and structurally characterized by X-ray single-crystal diffraction, elemental analyses, IR, TG- DTA and magnetic susceptibility measurement. It crystallizes in triclinic, space group P1 with a = 6.6842(5), b = 7.5741(6), c = 20.5755(15) , α = 90.1160(10), β = 97.0560(10), γ = 97.3350(10)°, V = 1025.16(13) 3, Z = 2, MnC24H14N6O5, Mr = 521.35, Dc = 1.689 g/cm3, F(000) = 530, μ(MoKa) = 0.699 mm-1, R = 0.0366 and wR = 0.0810. Compound 1 contains one- dimensional chains which are further stacked through π-π interactions to form a 3D supra- molecular architecture. The water molecule O(1W) is involved in hydrogen bonding interactions with symmetric carboxylate oxygen atom O(4) at (x+1, y+1, z) and symmetric PZDC nitrogen atom N(6) at (1–x, 1–y, 1–z), which completes the structure of 1. Magnetic susceptibility measurement indicates that the compound behaves a weak antiferromagnetic exchange inter- action.
