Stereoselective non-equivalent bis-diimine coordination to Co(II) ion: Structure, luminescence and density functional theory calculations

Stereoselective coordination of an unsymmetrical diimine (LNO2ϕ) affording only tcc-(LNO2ϕ1)(LNO2ϕ2)CoIICl20.25MeOH, a luminescent isomer of dihalobis(diimine)M(II) family, is reported (ϕ = dihedral angle between the diimine unit including pyridine ring and the phenyl ring planes).
