Six-coordinate tin in a dialkylchlorooxinatotin(IV) complex: skew-trapezoidal bipyramidal bis(2-carbomethoxyethyl)chloro(quinolin-8-olato)tin(IV)

Abstract Bis(2-carbomethoxyethyl)chloro(quinolin-8-olato)tin(IV), C17H20ClNO5Sn, crystallizes in the triclinic space group P 1 , with a 7.9001(7), b 10.2636(7), c 12.8287(9) A; α 108.575(7), β 98.564(6), γ 96.469(7)°; V 960.69 A3, Z = 2. The coordination geometry around the tin atom approximates to a skew-trapezoidal bipyramid, with the carbonyl oxygen of one of the 2-carbomethoxyethyl groups intramolecularly bonded to the tin (SnO 2.847(4) A). This oxygen atom, the nitrogen and oxygen atoms of the chelating quinolin-8-olato ligand (SnN 2.370(4), SnO 2.040(4) A; NSnO 74.4(1)°), and the chlorine atom (SnCl 2.454(2) A), occupy the four corners of a trapezoid around the metal atom. The two apical tincarbon bonds (SnC 2.122(6), 2.143(7) A), which are skewed towards the long edge (defined by the carbonyl oxygen and nitrogen atoms) of the trapezoidal plane, subtend an angle of 135.4(3)° at tin.
