“…Jensen and Nielsen (17) have observed that the spectra of sulfur and their corresponding selenium compounds are almost identical except that the bands connected with sulfur are shifted by about 30-100 cm-' lower in the selenium compounds. The force field for selenium compound is not expected to differ widely fiom that of the sulfur compounds.…”

The infrared spectrum of N,N-dimethyldithiocarbamate complex of nickel(I1) has been recorded in the range 2000-250 cm-'. Normal coordinate analyses have been made for nickel din~ethyldithio-carbamate and nickel dimethyldiselenocarban~ate colnplexes and their infrared spectra indexed. The frcquency shifts observed on alkyl substitution have been discussed. The M-Se stretching frequency occurs about 100 cm-' lower in the diselenocarba~nate con~plex as compared to M-S frcquency of the dithiocarbamate.

Abstract A series of alkyl-arylsubstituted N-methyl phosphinothioformamides, R(Ph)PC(S)NHMe (2 a-g), with varying bulkiness of the alkyl rest was synthesized from the racemic secondary phosphines 1a-g and methyl isothiocyanate. 1H and 13C NMR spectra of 2a−g reveal signal sets of diastereotopic nuclei due to the asymmetry of the molecule. The chemical shift and coupling constants were confirmed by simulation in case of 2b, c. The vicinal 31P−13C couplings of the menthyl and neomenthyl compounds 2f, g show an "anti-Karplus" behaviour (3J(gauche) > 3J(trans)) and allow the conformational assignment of the alicyclic group. The 31P chemical shifts of 2a−d give a linear correlation with the cone angle of the alkyl substituents quoted from literature.

Synthesis and characterization of complexes of Fe(II), Ni(II), Zn(II), Hg(II) and Cu(II) with two thiourea derivatives such as N- (2-methylphenyl), N'-(2,3-dimethylphenyl)thiourea (H 2 L 1 ) and N-(2-methylphenyl), N'-(2-chlorophenyl) thiourea (H 2 L 2 ) have been studied. Their structures were confirmed by IR spectroscopy. The ligands H 2 L 1 and H 2 L 2 used were prepared according to the procedure reported in the literature
