Synthesis and Crystal Structure of Coordination Compound of Cobalt(II) Pyridine-2,6-dicarboxylate with 1,10-phenanthroline

Cobalt pyridine-2,6-dicarboxylate ternary complex Co(DPC)(phen)(H_2O)]·2H_2O (C19H17CoN3O7, Mr=458.29) has been synthesized in the solution of cobaltous(II) chloride salt, where DPC=pyridine-2,6- dicarboxylate and phen=1,10-phenanthroline.The molecular and crystal structure was determined by single- crystal X-ray diffraction,the results indicate that the complex crystal is triclinic with space group P and unit cell parameters: a = 7.818(1), b=9.290(2), c=14.048(3)?; α=81.477(1), β=81.456(8), γ =72.970(2)°, V= 958.7(3)?3, Z=2, F(000)= 470, Dc =1.588Mg/m3, μ(MoKα)=0.944mm-1. In the structure the Co(II) ion is six-coordinated to form a distorted octahedron.
