Synthesis and spectroscopic characterization of tris(O,O '-ditolyl dithiophosphato) arsenic/antimony/bismuth(III) compounds: Crystal structures of [As{S2P(OC6H4Me-m)2}3]·0.5C6H14, [Sb{S2P(OC6H4Me-m)2}3] and [Bi{S2P(OC6H4Me-m)2}3]
Abstract
Arsenic(III), antimony(III) and bismuth(III) compounds of the type, [M{S<sub>2</sub>P(OR)<sub>2</sub>}<sub>3</sub>] (where M = As, Sb and Bi; R = o-, m-, p-C<sub>6</sub>H<sub>4</sub>Me) were obtained by reactions of MCl<sub>3</sub> with ammonium salts of the corresponding O,O'-ditolyl dithiophosphate on refluxing in benzene. These compounds were characterized by elemental analysis, IR, H-1 NMR and P-31 NMR spectroscopy. The single crystal X-ray structures of three representative compounds were determined. [As{S<sub>2</sub>P(OC<sub>6</sub>H<sub>4</sub>Me-m)<sub>2</sub>}<sub>3</sub>] · 0.5C<sub>6</sub>H<sub>14</sub> crystallizes as triclinic in the space group P (1) over bar with a = 10.9396(1), b = 14.1891(2), c = 17.5359(2) angstrom, alpha = 70.731(1), beta = 84.734(1), gamma = 74.205(1)degrees, Z = 4,V = 2472.37(5) angstrom(3). [Sb{S<sub>2</sub>P(OC<sub>6</sub>H<sub>4</sub>Me-m)<sub>2</sub>}<sub>3</sub>] and [Bi{S<sub>2</sub>P(OC<sub>6</sub>H<sub>4</sub>Me-m)<sub>2</sub>}<sub>3</sub>] both crystallize as monoclinic in the space group P2(1) with a = 12.4520(3), b = 22.8760(5), c = 16.2165(4) angstrom, beta = 93.022(1)degrees, Z = 4, V = 4612.9(2) angstrom(3) and with a = 12.4903(2), b = 22.9554(4), c = 16.1032(3)angstrom, beta = 92.4300(10)degrees, Z = 4, V = 4612.96(14) angstrom(3), respectively. In all three molecules, the central metal atom is surrounded by all six sulfur atoms of the three chelating anisobidentate O,O'-ditolyl dithiophosphate groups in a pseudo trigonally distorted octahedron with a lone pair positioned on one of the triangular octahedral faces. The three metal sulfur bonds adjacent to the lone pair (capped face) are longer than the three furthest from the lone pair (uncapped face). Inter-ligand angles between the longer bonds are greater than those between the shorter bonds.
