The one pot synthesis of heterobimetallic complexes from a homoditopic pyrimidine–hydrazone ligand

Author affiliations

Abstract

The symmetrical, homoditopic, pyrimidine-hydrazone (pym-hyz) ligand L1 was used to synthesise three new heterobimetallic complexes, CuPbL1(ClO4)4, CuAgL1(SO3CF3)3, and CuZnL1(SO3CF3)4. Each of the complexes was produced in a one-pot reaction in CH3CN, and was isolated in high yield and purity simply by precipitation through the addition of diethyl ether. Analysis was carried out by IR, UV-Vis and ESMS spectroscopy, as well as microanalysis. Crystals were also grown for the purposes of X-ray diffraction studies, which yielded the structures [CuPbL1(ClO4)(CH3CN)2(H2O)](ClO4)3 (1), [CuAgL1(SO3CF3)(CH3CN)2](SO3CF3)2·CH3CN (2), and CuZnL1(SO3CF3)2(CH3CN)(H2O)](SO3CF3)2·CH3CN (3), all of which were linear complexes containing a Cu(II) ion in one of the pym-hyz-py coordination sites, and either a Pb(II), Ag(I), or Zn(II) ion in the other.
