Complexes of Pyridine-2-carbaldehyde S-Methylthiosemicarbazone with nickel(II) and copper(II)
Keyword(s):
New complexes of pyridine-2-carbaldehyde S-methylthiosemicarbazone (pmts) with nickel(11) and copper(11) are reported, together with magnetic moments, infrared and electronic spectra. The pale yellow bis-ligand complexes with nickel perchlorate, tetrafluoroborate and nitrate have the ionic structures [Ni(pmts)2] X2, with six-coordinate nickel(11) and tridentate ligands. Thiocyanate co-ordination and bidentate pmts appear to be present in the six-coordinate orange-brown complex Ni(pmts)2(NCs)2. The complexes, Ni(pmts)X2 (X = Cl, Br), are halogen-bridged and six-coordinate. The complexes Cu(pmts)X2 (X = Cl, Br, NO3) do not appear to be five coordinate, and may be six coordinate.
