摘 要: | A manganese(Ⅱ) complex (tataH)2Mn(pydc)2]·4H2O (C20H28MBN14O12, 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)A, a = 101.5310(10), β = 90.2610(10), γ = 116.4600( 10)% V = 1459.44(8)A^3, Z = 2, Dc = 1.619 g/cm^3,μ = 0.539 mm^-1, F(000) = 734, the final R = 0.0292 and wR = 0.0745. In the crystal the Mnn 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.
