Synthesis and characterization of three hetero-dinuclear complexes with CuO2M cores (M = Na, Hg): Exploration of their phenoxazinone synthase mimicking activity

Three new hetero-dinuclear complexes, [(CuLNa)-Na-1(NCS)]center dot 0.5H(2)O (1), [(CuLNa)-Na-1(OClO3)]center dot 0.25H(2)O (2) and [(CuLHgCl2)-Hg-2] (3) (where H2L1 = N,N'-bis(3-ethoxysalicylidene)-2,2-dimethylpropane-1,3-diamine and H2L2 = N,N'-bis(3-methoxysalicylidene)-2,2-dimethylpropane-1,3-diamine] are N2O4 donor compartmental Schiff bases) have been synthesized and characterized. The phenoxazinone synthase mimicking activity of each complex in acetonitrile has been investigated with the model substrate o-aminophenol. (C) 2018 Elsevier Ltd. All rights reserved.
