Structural comparison of CuIand CuIIcomplexes displaying analogous N2S2co-ordination; X-ray analysis of tetraco-ordinate [Cu(pma)]BPh4and pentaco-ordinate [Cu(pma)SO4][pma2-pyridylmethylbis-(2-ethylthioethyl)amine

Abstract

The synthesis and X-ray structural characterization of the CuI and CuII complexes [Cu(pma)]BPh4 and [Cu(pma)SO4][pma2-pyridylmethylbis-(2-ethylthioethyl)amine] are reported; both display N2S2 co-ordination with the CuI complex exhibiting trigonal pyramidal geometry while the CuII derivative shows a distorted trigonal bipyramidal geometry which includes a co-ordinated sulphate group.
