one aroylhydrazone moiety, leaving the other one uncoordinated. The X-ray crystal structures of [Co(HL2–CH3)(L2–CH3)] and [Co(HL1–R)2]Cl (R = H, CH3) show that the molecular units are assembled into dimers through π–π stacking and hydrogen-bonded interactions respectively in the neutral and cationic complexes. Both types of dimers are linked together giving linear chains which in turn are interconnected
