Structure of bis[bis(2-hydroxyethyl)dithiocarbamato]tellurium(II), [Te(C5H10NO2S2)2]

Structure of bis(dipropyldithiocarbamato)tellurium(II)

“…The bonding in such square-planar complexes can be explained in terms of three-centre four-electron bonding (Fabiani, Spagna, Vaciago & Zambonelli, 1971;Foss, 1967Foss, , 1970. The same behaviour is also followed in most cases by Se n complexes (Husebye & Helland-Madsen, 1970;Rout, Seshasayee, Radha & Aravamudan, 1983).…”

“…All the terminal C atoms showed large movements as indicated by their high thermal factors. Disorder is observed in similar compounds for the terminal atoms (Rout, Seshasayee, Radha & Aravamudan, 1983). Fullmatrix least-squares refinement on F using SHELX76 (Sheldrick, 1976) with anisotropic thermal parameters for non-H atoms except for the disordered C(4) and C(4a) positions which were refined isotropically.…”

Main Group Dithiocarbamate Complexes

“…Homoleptic dithiocarbamate complexes of both tellurium(II) (215,293,294,296,(302)(303)(304)(305)(306)(307)(308)(309)(310)(311) and tellurium(IV) (293, 294, 296, 302, 304-306, 309, 310, 312-315) are well known. The molecular structures of the bis(dithiocarbamate)tellurium(II) compounds, [Te(S 2 CNR 2 ) 2 ], are analogous to those of the corresponding Se compounds: The Te atom exhibits a planar trapezoidal coordination geometry, with the two dithiocarbamate ligands bound in an anisobidentate fashion [TeÀ ÀS(ave) ¼ 2.52 (short) and 2.83 A ˚(long)].…”

Redetermination of tris(N,N-diethyldithiocarbamato)antimony(III)

“…The dithiocarbamate anion (R 1 R 2 NCS 2-=I -) is known to be a strong nucleophile and to form stable complexs with many post-transition metals (Coucouvanis, 1979). Thus, complexes involving Te(IV), Te(II) and Se(II) centres have been reported, and structural studies on these have shown the presence of bidentate chelating ligands (Husebye et al, 1973;Rout et al, 1983). We have synthesized the title compound, C 15 H 30 N 3 S 6 Sb, and report here its crystal structure.…”
