Abstract
Mononuclear O,O-coordinated complexes K2(MLCl2) M = Zn(II), Cd(II) and dinuclear complexes (MZnLCl2R2)x along with dinuclear N,N-coordinated complexes (M′ZnH2LCl2R2)y (where M = Zn(II), Cd(II), Hg(II) and M′ = M and Sn(IV); R = Cl, CH3; x = 0, −2; y = 0, +2) of N′-1-,N′-2-dihydroxy-N-1-,N-2-dipyridin-2-ylethanedimidamide (H2L) have been prepared. All complexes have been characterized by 1H NMR, IR, EI-mass spectroscopy and elemental microanalysis. These results are in agreement with our prediction for structures of mono and dinuclear complexes of H2L and L−2 with Zn(II) in the gas phase by theoretical studies.
