Abstract
N-Triphenylstannyl-1,2-benzisothiazol-3(2H)-one 1,1-dioxide crystallizes from ethanol as the adduct, [SO2C6H4C(O)NSn(C6H5)3·C2H5OH], in the monoclinic space group P21 with a 9.460(2), b 16.338(1), c 9.580(2) A, β 113.76(2)°; Z = 2. The molecule is monomeric and five-coordinate at tin. The coordination geometry is distorted trans-C3SnNO trigonal bipyramidal, with the ipso-carbons (SnC 2.111(5), 2.120(8), 2.128(7) A) of the phenyl rings lying in the equatorial plane and the axial positions occupied by the imido nitrogen atom of the saccharin (SnN 2.240(7) A) and the ethanolic oxygen atom (SnO 2.394(8) A). The tin atom is displaced from the equatorial plane by 0.221(1) A in the direction of the apical nitrogen. The compound is an unusual example of an organotin complex containing coordinated ethanol.
