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)center dot CH3CN (2), and CuZnL1(SO3CF3)(2)(CH3CN)(H2O)](SO3CF3)(2)center dot 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.
