Syntheses and crystal structures of two polymorphs of the complex [Co(II)(L)], where H2L = 2,2’-[cis-1,2-diaminocyclohexanediylbis (nitrilo-methylidyne)]bis (5-dimethyl-amino]phenol, have been studied. The two polymorphs concomitantly crystallized by vapour diffusion of solvent. The first polymorph (I) crystallized as a racemate in the centrosymmetric tetragonal I41/a space group. The second polymorph (II) crystallized in the chiral orthorhombic space group P212121. The chiral conformers of symmetrical cis-1,2-disubstituted cyclohexane molecules cannot be resolved in the liquid or gas phases, due to the rapid ring inversion. In the present study, the two chiral conformers are present in crystals of polymorph I, whereas, only one chiral conformer is present in crystals of polymorph II. Crystal structure analysis indicated that the formation of two different polymorphs of [Co(II)(L)] complex can be rationalized based on CH⋯Co anagostic interactions. Density Functional Theory (DFT) calculations indicated that CH⋯Co interactions are due to HOMO-LUMO interactions.
