title: The low-temperature phase of di-tert-butylsilanediol.
abstract: The crystal structure of di-tert-butylsilanediol, C(8)H(20)O(2)Si, has a reversible phase transition at 211 (2) K. The orthorhombic high-temperature structure has space group Ibam, with Z' = 1/2, and shows a disordered hydrogen-bonding system. The low-temperature structure, determined at 143 (2) K, has a twinned monoclinic cell, with space group C2/c and Z' = 2, and shows an ordered hydrogen-bonding system.
