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

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; R 1 = 0.0585, wR 2 = 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.
