Abstract Hexa-terf-butyldisiloxane (tBu 3 Si) 2 O (2), hexa-rerr-butyldisilazane (tBu 3 Si) 2 NH (3), and the disiloxane (tBu 3 SiNHSuBu 2 ) 2 O (4) are prepared from bis(silyl)triazene tBu 3 SiN=N-NHSirBu 3 by reaction with water (2) and by thermolysis (3), or from silanimine tBu 2 Si=NSirBu 3 by reaction with water (4). Structures of 2-4 have been determined by X-ray crystallography (for data cf. Tables II). As a consequence of the bulkiness of the silyl groups, the heavy atom frameworks SiOSi in 2 and 4 are linear, and the SiNSi angles in 3 (167 ± 2°) and 4 (157.1°) are comparatively large.
