Bis(2-carbomethoxyethyl)chloro(quinolin-8-olato)tin(IV), C17H20ClNO5Sn, crystallizes in the triclinic space group P1, with a 7.9001(7), b 10.2636(7), c 12.8287(9) Å; α 108.575(7), β 98.564(6), γ 96.469(7)°; V 960.69 Å3, 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 (SnO 2.847(4) Å). This oxygen atom, the nitrogen and oxygen atoms of the chelating quinolin-8-olato ligand (SnN 2.370(4), SnO 2.040(4) Å; NSnO 74.4(1)°), and the chlorine atom (SnCl 2.454(2) Å), occupy the four corners of a trapezoid around the metal atom. The two apical tincarbon bonds (SnC 2.122(6), 2.143(7) Å), 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.
