Synthesis and Characterization of Trinuclear Complexes Containing Cu(II) and Ti(IV)

Abstract

Abstract Heterotrinuclear complexes of the type [Cu(ppn)2Cl2{Ti(Cp)2}2] and [Cu(en)2(NO3)2{Ti(Cp)2}2] have been synthesized and characterized by elemental analyses, IR, electronic, EPR, and 1H NMR spectra, magnetic moments, and conductivity measurements. The results indicate that the trinuclear complexes are covalent with an octahedral environment around the copper(II) ion, while its mononuclear analogues, [Cu(ppn‐H2)2]Cl2 and [Cu(en‐H2)2](NO3)2, are square‐planar and ionic in nature.
