 Title    Die Hydrate von terf-Butanol: Kristallstruktur von Me3COH * 2 H20 und Me3COH * 7 H20 [ 1 ]  
 Abstract    The system /er/-butanol-water has been confirmed by X-ray powder diffraction and single­ crystal structure analysis to contain two hydrates, a dihydrate and a higher hydrate. The com ­ position o f the latter, contradictory in the literature, could be resolved in favor o f the new one o f a heptahydrate. The dihydrate (m.p. 0.7 °C) is m onoclinic with space group P2, and Z = 2 formula units per unit cell o f dim ensions a = 6.017, b = 6.055, c = 10.377 A and ß -106.60° at -150 °C. The heptahydrate (m.p. -6 °C, dec.) is orthorhombic with space group Pnma, Z = 4, a -12.589, b = 15.251 and c = 6.645 A at -150 °C. Both hydrates contain characteristic layers o f hydrogen-bonded O atom s, which in the heptahydrate are further linked into a three-di-m ensional semi-clathrate structure.
