Coordination chemistry; nickel(II); cobalt(III); Schiff base; twisted helicity; supramolecular interactions.

Two mononuclear complexes namely [Ni^II(L)] (1) and [Co^III(L)](NO₃) (2) of a hexacoordinating N₄O₂ donor Schiff base ligand were synthesized and characterized by single crystal X-ray studies. In compound 2 the central cobalt is in +3 oxidation state while `in' compound 2, the nickel ion is in +2 oxidation state. The two complexes are isostructural with octahedral coordination environment exhibiting helical twist topology. They also display strong H-bonding as well as CH-𝜋 interactions to generate 1D chain.
