S. Ramaprabhu et al., N-ALKYLIMIDAZOLIDINE-2-THIONE DIHALOGENOCUPRATE ANIONS - PREPARATION,STRUCTURE AND NUCLEAR-QUADRUPOLE RESONANCE-SPECTRA, Journal of chemical research. Synopses, (10), 1994, pp. 368-369
The synthesis and Cu-63 NQR spectra of five tetraethylammonium N-alkyl
imidazolidine-2-thione dihalogenocuprate(i) complexes are reported alo
ng with the crystal structure of one of them, tetraethylammonium (N-me
thylimidazoline-2-thione) CuBr2 (2), which reveals a planar three-coor
dinate anion; the Br-81 NQR spectra for 2 and for the corresponding N-
ethylimidazoline-2-thione complex were also observed.
