Crystal Structure of p-Tolylbis (diethyldithiocarbamato)thallium(III) and Phenylbis-(methylxanthogenato)bismut(III)The crystal structure of 4-CH3(C6H4)—Tl(S2CN(C2H5)2)2 (P21/c, a = 11.973(3), b = 10.692(3), c = 19.232(4) Å, β = 114.02(2)°, Z = 4) and C6H5-Bi(S2COCH3)2 (P21/c, a = 6.395(2), b = 24.684(8), c = 9.732(3) Å, β = 101.38(3)°, Z = 4) was solved from X-ray diffraction data of single crystals. From the interatomic distances follows that the dithiocarbamate and xanthogenate ligands coordinate asymmetrically bidentate to the metal as presumed and exclusively through the sulfur atoms. Differences in the coordination sphere of bismut and thallium give evidence for a “stereochemically active lone pair” on the bismut atom.
Notes:
Die Kristallstruktur von 4-CH3(C6H4)—Tl(S2CN(C2H5)2)2 (P21/c, a = 11,973(3) Å, b = 10,692(3) Å, c = 19,232(4) Å, β = 114,02(2)°, Z = 4) und C6H5-Bi(S2COCH3)2 (P21/c, a = 6,395(2) Å, b = 24,684(8) Å, c = 9,732(3) Å, β = 101,38(3)°, Z = 4) konnte aus Röntgendiffraktometerdaten von Einkristallen ermittelt werden. Die interatomaren Abstände zeigen daß, die Koordination von Dithiocarbamat und Xanthogenat an die Metallatome wie schon vermutet stark asymmetrisch zweizähnig und ausschließlich über Schwefel erfolgt. Die Koordinationsunterschiede zwischen Bismut und Thallium ergeben ein deutliches Indiz für die “stereochemische Aktivität” des freien Elektronenpaares am Bismutatom.
