Twin salphen: asymmetric heterodinuclear complexes {M(a)M(b)L | M(a), M(b) = Ni, Cu, Zn} of a symmetrically fused salphen ligand.
Heterodinuclear complexes of a fully pi-conjugated salphen ligand were efficiently synthesized with arbitrary combinations of Ni(II), Cu(II), and Zn(II). The UV-vis spectra of the heterodinuclear complexes were approximately represented by a simple average of the spectra of the corresponding homodinuclear complexes. Systematic analysis of the spectra highlighted weak intracomplex interactions through the pi-conjugated system of the ligand.
