The pentavalent silicon in the title compound is coordinated by four oxygen atoms. The N→Si dative bond is rather short (2.079(2) Å). The crystal structure is partially disordered: carbon atoms attached to nitrogen appear on both sides of the SiO(eq)C, N plane with a population of 0.8 and 0.2, respectively. The change of the configuration around silicon and nitrogen, as a function of the N→Si dative bond length, is reviewed for several silatrane structures. Structural data suggest that different extents of the distortion of the trigonal bipyramid around silicon for the various compounds may represent stages along the pathway of the SN2-type reaction SiX + HN → SiN.
