The title compound [Co (C7H8N4O)2]Cl2.3H2O, has been synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The title compound crystallizes in a triclinic, space group P-1 with a = 9.3547(5) Å, b = 9.8985(5) Å, c = 12.8840(7) Å, α=106.033(4)º, β = 103.916(4)º, γ = 95.717(4)º, V = 1095.20(10) Å3, Z=2, R = 0.0255 and wR = 0.0687. In the title compound there are two crystallographically independent cations and anions and three water molecules in the asymmetric unit. The CoII ion has a distorted octahedral coordination environment and is surrounded by four N atoms and two O atoms in a tridentate manner. In the crystal, N—H…Cl, N—H…O, O—H…Cl and O—H…O hydrogen bonds link the complex cations, chloride anions and solvent water molecules into a three-dimensional network. The preliminary antimicrobial activities were studied.

Keywords :

X-ray diffraction; octahedral coordination; tridentate; hydrogen bonds; antimicrobial activity.
