Abstract

The syntheses and structures of the novel Ce–Fe bimetallic complexes [{Fe(sal)2(bpy)}2Ce(NO3)(H2O)3]·EtOH and [{Fe(sal)2(bpy)}4Ce2(H2O)11][salH]2·EtOH·3H2O (salH2 = salicylic acid) suggest Fe3+–sal2? units and Ce–OC(R)O–Fe bridging contribute to the formation of corrosion inhibitive layers on steel surfaces exposed to [Ce(salH)3(H2O)].
