The electrochemical oxidation of a sacrificial anode (M = Zn, Cd, Hg, In, Sn) in non-aqueous solutions of 3-hydroxyflavone, 1'-hydroxy-2'-acetonaphthone, or 2-ethoxyphenol (=HL) gives ZnL2, CdL2, HgL, InL3, or SnL2 (not all combinations).Adducts with 2,2'-bipyridine (bpy) or N,N,N',N'-tetramethylethanediamine (tmen) have also been prepared in some cases.Certain zinc and cadmium compounds produce paramagnetic species on exposure to the atmosphere.The structure of Zn(C15H9O3)2tmen has been determined; the crystals are orthorhombic, space group Pbcn, cell dimensions a=18.817(2) Angstroem, b=13.886(3) Angstroem, c=12.567(3) Angstroem, Z=4, R=0.0758 for 773 unique observed reflections.The corresponding data for Cd(C12H9O2)2bpy are orthorhombic, space group Pbca, cell dimensions a=20.338(4) Angstroem, b=30.473(5) Angstroem, c=9.316(2) Angstroem, Z=8, R=0.0457 for 2623 unique observed reflections.Both molecules have MO4N2 kernels, but each shows significant differences in the two M-O bond lenghts to the dioxo ligand, and there are concomitant effects in the C-O and C-C bond distances in the ligands.
