The crystal structure of a 1,2-disilanediol, (t-Bu2-SiOH)2
摘要:
The synthesis and structure of the first 1,2-disilanediol, (t-Bu2SiOH)2 (2) is reported. Crystal data: 2, triclinic, PBAR1 (No. 2), a 9.486(3), b 16.680(3), c 10.681(4) angstrom, alpha-76.71(2), beta-85.10(2), gamma-78.59(2)-degrees, and Z = 2. The unit cell of 2 contains two discrete monomers hydrogen-bonded as a chain. The long distances for Si-Si (2.453 angstrom) and Si-C (1.88 angstrom) bonds in 2 indicate a high degree of steric strain in this molecule.
