Popis: Bis(tetraphenylantimony) 1,2-diphenylethanedione dioximate toluene solvate Ph4SbONC(Ph)C(Ph)NOSbPh4 · 2 PhCH3 (I) and tetraphenylantimony 2-hydroxy-1,2-diphenyl(ethanone oximate Ph4SbONC(Ph)CH(Ph)OH (II) have been synthesized by the reaction of pentaphenylantimony with 1,2-diphenylethane dioxime and 2-hydroxy-1,2-diphenylethanone oxime in toluene. A molecule of compound I is centrosymmetric with an inversion center at the midpoint of the C-C bond in the ethane moiety. A crystal of compound II contains two types of crystallographically independent molecules A and B. Antimony atoms in compounds I and II have a distorted tetragonal bipyramidal surrounding: equatorial CSbC and axial CSbO angles are 114.95(10)°–126.82(11)° and 173.24(9)° (I), 117.2(2)°–122.9(2)° and 178.15(18)° (IIA), and 112.3(2)°–127.7(2)° and 175.09(18)° (IIB), respectively. The Sb-C and Sb-O bond lengths are 2.106(3)–2.182(3) and 2.1344(17) AI), 2.118(5)–2.4199(5) and 2.153(4)A(IIA), and 2.106(5)–2.200(5) and 2.120(4) A (IIB), respectively. A molecule of compounds I, IIA, and IIB has been found to contain Sb...N intramolecular contacts (2.838(3), 2.867(5), and 2.889(5)A, respectively). Molecules of compounds IIA and IIB contain O-H...N hydrogen bonds (H...N, 1.91(9) and 2.06(8) A, respectively).
