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)(H2O)]. 2H(2)O (C19H17CoN3O7, M-r=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 P1 and unit cell parameters: a = 7.818(1), b=9.290(2), c=14.048(3)Angstrom; alpha =81.477(1),beta =81.456(8), gamma =72.970(2)degrees, V= 958.7(3)Angstrom (3), Z=2, F(000)= 470, D-c =1.588Mg/m, mu (MoK alpha)--0.944mm(-1). In the structure the Co(II) ion is six-coordinated to form a distorted octahedron.
