Sterically crowded stannyl azides tBunSn(N3)4-n (IIa,b) have been prepared for the first time by the reactions of stannylamines tBunSn(NHR)4-n (Ia,b) with Me3SiN3 (a: n = 3, R = H; b: n = 2, R = tBu).The novel compounds were characterized by NMR (1H, 13C) and mass spectroscopy and their molecular structure determined by X-ray crystallography (IIa: space group P21/m, Z = 2; IIb: space group P21/n, Z = 4). Keywords: Tin; Stannyl azides; Synthesis; X-ray structure
