A manganese(II) complex (tataH)2[Mn(pydc)2]·4H2O (C20H28MnN14O12, Mr = 711.50, tata = 2,4,6-triamino-1,3,5-triazine, pydcH2 = pyridine-2,6-dicarboxylic acid) has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to the triclinic system, space group P1, with a = 9.9847(3), b = 10.9813(3), c = 15.2616(5) , α = 101.5310(10), β = 90.2610(10), γ = 116.4600(10)°, V = 1459.44(8) 3, Z = 2, Dc = 1.619 g/cm3, μ = 0.539 mm–1, F(000) = 734, the final R = 0.0292 and wR = 0.0745. In the crystal the MnII atom is six-coordinated by four carbonyl oxygen atoms and two pyridine nitrogen atoms from two tridentate pydc ligands to furnish a distorted octahedral geometry. The complex shows the A…D…D’…A’ H-bonded tetramer. The molecules are packed in a three-dimensional framework structure by the combination of O–H…O, N–H…O and N–H…N hydrogen bonds between (tataH)+, [Mn(pydc)2]2– and crystal water.
