S. Rajashree et al., THE HEMI-ADDUCT OF BIS(DIETHYLDITHIOCARBAMATO-S,S')-TELLURIUM(II) WITH 4,4'-BIPYRIDYL, Acta crystallographica. Section C, Crystal structure communications, 52, 1996, pp. 707-709
In the structure of dithiocarbamato-S,S')-tellurium(II)-4,4'-bipyridyl
(2/1), [Te(C5H10NS2)(2)].-1/2C(10)H(8)N(2), the bipyridyl molecule wa
s found to bridge two bis(diethyldithiocarbamato)tellurium moieties ce
ntrosymmetrically, i.e. l-N:N')-bis(diethyldithiocarbamato-S,S')tellur
ium. The N atom of the bipyridyl is very weakly coordinated to telluri
um and this is the first instance of Te-N coordination observed in a t
ellurium-dithiocarbamate complex. Each Te atom has an unusual planar-p
entagonal arrangement of ligands around it.
