Tetra(para-tolyl)Antimony 4-nitrobenzaldoximate solvate with benzene p-Tol4SbON=CHC6H4(NO2-4)∙PhH. Synthesis and structure

Abstract

The p-Tol4SbON=CHC6H4(NO2-4)∙PhH solvate (1) has been synthesized by interaction of equimolar amounts of penta(para-tolyl)antimony and 4-nitrobenzaldoxime in benzene, they it has been structurally characterized. according to X-ray diffraction analysis performed at 293 K on an automatic four-circle diffractometer D8 Quest Bruker (two-coordinate CCD detector, Mo Kα radiation, λ = 0.71073 Å, graphite monochromator), crystals 1 [C41H39N2O3Sb, M 729.85; monoclinic system, space group Р21/n; cell parameters: a = 10.332(4), b = 34.482(16), c = 10.631(6) Å; β = 100.172(13) град.; V = 3728(3) Å3; crystal size 0.5 × 0.45 × 0.26 mm; index ranges –14 ≤ h ≤ 13, –49 ≤ k ≤ 49, –15 ≤ l ≤ 15; total reflections 116265; independent reflections 11360; Rint 0.0479; GOOF 1.250; R1 = 0.0585, wR2 = 0.1089; residual electron density 1.14/−2.74 e/Å3], have a distorted trigonal-bipyramidal coordination with the carbon and oxygen atoms in axial positions (axial angles are 175.63(11)°). The Sb–O distances are 2.151(2) Å, the Sb–C bond lengths vary within a narrow range of values (2.115(4)−2.193(3) Å). Structural organization in crystals is due to weak intermolecular contacts of the O•••H type 2.47–2.68 Å.
