Structure analysis of triaryl derivatives of the group V elements III. Molecular Structure and Spectra of Tris(2,6-Dimethylphenyl)Stibine, C24H27Sb

Crystal Structures of Tri(o-Tolyl)stibine in Two Crystal Forms

“…It is noteworthy that the mean value of the angle C-Sb-C in (1) is 97.4(3)°and 96.66(2)° in (2) is much similar 97.3(1)° found in tri(p-tolyl)stibine [3] but significantly smaller than the angles 105.3°, 104.7(2)° found in 2,4,6-trimesitylstibine and tris-(2,6-dimethylphenyl)stibine respectively [1,2].…”

“…The attempted reaction of tri(o-tolyl)stibine with a solution of cobalt chloride in methanol at 80|C resulted , upon concentration, crystals of tri(o-tolyl)stibine in triclinic form (2). The IR and "H NMR spectra were compared with that in literature [5], Ο C11 Fig.…”

“…The literature shows that the C-Sb-C angles in triaryl derivatives of antimony range from 105.3° in (Mesityl) 3 Sb [1], 104.7° (2) in (2,6 dimethylphenyl) 3 Sb [2], 97.3°(1) in (p-tolyl) 3 Sb [3] to 95.0° (3) in Ph 3 Sb [4], In order to get more complete and detailed data on such structures, we have performed X-ray structure analysis of tri(o-tolyl)stibine C2iH 2 iSb. X-ray crystal structure of tri(o-tolyl)stibine has been determined in two different crystal forms.…”

First synthesis and structural report on selenophen-2-yl containing pnictogens: Biological activities of tris(selenophen-2-yl)stibine

“…The average Sb-C bond length found in 1 is 2.127 Å , which is slightly shorter than that found in other known tertiary stibines [28][29][30][31], e.g., Ph 3 Sb 2.155; 2.190 in tris(2,6-dimethylphenyl)stibine; 2.158 in tris(2-methylphenyl)stibine. This may be due to the pp-dp* bonding to a greater extent and thus shortening of Sb-C bond length and is similar to (C 4 H 3 S) 3 Sb where C-Sb (av) is 2.129 Å [5].…”

Substituted thienyl stibines and bismuthines: syntheses, structures and cytotoxicity

“…In compound 3, S(6), C(7) and C(10) were refined to a site populations of 0.661 (9), and their disordered congeners S(6B), C(7B) and C(10B) are complementary. For compound 4, the refined site populations converged to 0.620 (18) and 0.380 (18) for S(1) and C(5) respectively, as well as for S(1B) and C(5B).…”
