[M2(L)(Cl)x(NH3)y]·zH2O where (M = Ru3+, Pt4+ and Ir3+, L = deprotonated Schiff base of o-vanilin p-amino acetophenone, x = 5, y = 4, z = 0 for Ru3+ (1) and Ir3+ (3) and x = 7, y = 2, z = 3 for Pt4+ (2)) were synthesized. In ethanol, the Schiff base (HL) was prepared by refluxing o-vanilin with p-aminoacetophenone. Ru3+, Pt4+ and Ir3+ chelates of The Schiff base coordinated to the tested metal ions (Ru3+
