Abstract: The crystal and molecular structure of the monoclinic phase of 1,3-ti-tert-butyl-2,2-dimethyl-1,3,2,4l²-diazasiastannetidine has been determined from thress-dimensional X-ray data collected on a two-circle diffractometer at - 120°C (MoKa radiation, 2623 reflexions, R=0,050). The crystals are monoclinic, space group C2/c, with cell dimensions a = 10.655(5), b=25.75(1), c=17.33(1) A, beta=106.8(l)° and Z=12. Four monomeric (crystal site symmetry 2 (C2)) and four dimeric units (crystal site symmetry l(C1)) are present in the structure interaction over tin-tin 3.68 A) Remarkable are the very short Sn-N bond (2.09 A) in the monomer and the donation bond Sn-N (2.39 A) in the dimer. The coordination of the tin atoms in the different units is discussed in detail.
