T. Okamura et al., THE EFFECT OF STRONG NHS HYDROGEN-BONDS IN THE COPPER(I) THIOLATE COMPLEX, (NET4)2[CU(O-PABT)3] (O-PABT = O-PIVALOYLAMINOBENZENETHIOLATO), Journal of the Chemical Society, Chemical Communications, (21), 1993, pp. 1658-1660
Short Cu-S bonds, induced by strong intramolecular NH...S hydrogen bon
ds, have been established by X-ray analysis, IR spectra, and EHMO calc
ulations for (NEt4)2[Cu(I)(o-pabt)3] (o-pabt = o-pivaloylaminobenzenet
hiolato) and suggest an important role for this type of hydrogen bondi
ng in blue copper proteins.
