Abstract

Four copper(II) complexes, [Cu2(DpyMeTsc)2SO4]·3H2O (1), [Cu(DpyMeTsc)N3]·H2O (2), [Cu2(DpyMeTsc)2]·(ClO4)2·2H2O (3), and [Cu(DpyMeTsc)(CH3COO)]·2H2O (4) of di-2-pyridyl ketone N(4)-methylthiosemicarbazone (HDpyMeTsc) are studied with electron paramagnetic resonance (EPR) spectroscopy. EPR is the most powerful spectroscopic method to discriminate between monomeric and dimeric Cu(II) complexes in solution. EPR studies indicate dimeric nature of (1) and (3) and monomeric nature of (2) and (4).
