New Copper and Oxomolybdate Robson-Type Polynuclear Macrocyclic Complexes: Structure, Spectroscopy, and Electrochemical Properties

The polynuclear complexes [Mo3O8(tidf)]·dmso·2H2O (1) and [{Cu2(tidf)}2(μ-Mo8O24)] (2) (tidf2− is a symmetrical tetraiminodiphenolate Robson-type macrocyclic ligand) were prepared from equimolar combinations of [Mg2(tidf)](NO3)2·4H2O, [MoO2Cl2(dmso)2] (for 1) and complex 1 and Cu(ClO4)2·4H2O (for 2)...
