S. Knoll et al., COMPLEXES OF ZN(II) WITH SCHIFF-BASES OF HYDRAZINE-O-METHYLCARBOTHIONATES - NMR-SPECTROSCOPIC INVESTIGATIONS, Journal fur praktische Chemie, Chemiker-Zeitung, 338(1), 1996, pp. 60-64
Schiff bases of hydrazine-O-methylcarbothionates react as bi- or tride
ntate ligands with Zn(II) ions forming neutral metal complexes (1a-1g)
. H-1-, C-13- and N-15-NMR-spectra of these complexes show the existen
ce of configurational isomers of the C = N-double bond. Furthermore, d
epending on the ligands 4 different coordination patterns with the don
or atoms N2S2, N-4, N2O2 and NOS are demonstrated.
