Copper(II)–N2S2 complexes of bidentate N-substituted β-aminothiones
Abstract
Bis(α,β-unsaturated N-substituted β-aminothione) CuII complexes, synthesised at low temperature, show intense S → Cu charge-transfer bands and have e.s.r. spectra with small |Az|(Cu) indicative of pseudo-tetrahedral CuN2S2 co-ordination similar to that found for the type 1 centres in blue copper proteins.
