Abstract The crystal structure of the title compound, (CH3)2Sn(C6H4O) CHN(OC6H4), has been determined from X-ray diffractometer data by Patterson and Fourier methods. The crystals are orthorhombic, space groupPbcn witha =19.304,b = 10.534,c = 13.398 Å andZ = 8. Full-matrix least-squares refinement of the 1024 reflexions having ¦F¦2 〉σ(¦F¦2) led toR = 0.044. The tin atom is pentacoordinate with the two oxygen atoms forming the apices and the two methyl groups and nitrogen atom forming the equatorial plane of a distorted trigonal bypyramid. The Schiff base ligand is thus tridentate. The bond lengths involving the tin atom are Sn-O, 2.108(6) and 2.130(6); Sn-N, 2.224(8); Sn-C, 2.10(1) and 2.12(1) Å.
