Abstract
The coblat complex with molecular formula [C26H30Cl2CoN2O2, Mr = 532.35] has been synthesized and characterized by elemental analysis and X-ray diffraction. As expected, the molecular structure adopts a trans configuration about the C=N double bond. It crystallizes in monoclinic system, space group Pbca with a = 14.875(3) Å, b = 13.569(2) Å, c = 24.957(5) Å, b = 90º, V = 5037.6(14) Å3, Z = 8, Dc = 1.404 Mg/m3, F(000) =2216, μ(MoKa) = 0.919 m m-1, R = 0.0415 and wR = 0.0492 of the 5667 collection, 4690 were unique. The title compound, [C26H30Cl2N2O2] is a mononuclear cobalt(II) complex. The Co atom is four-coordinated by two N atoms and two O atoms from two Schiff base ligands in a slightly distorted tetrahedral geometry.
