INCLUSION-COMPOUNDS OF HYDROXY HOSTS .6. STRUCTURES AND THERMAL-ANALYSIS OF 1,2,3,4,5-PENTAPHENYLCYCLOPENTA-2,4-DIEN-1-OL WITH METHANOL AND ETHANOL

The crystal and molecular structures of the methanol and ethanol inclusion compounds of 1,2,3,4,5-pentaphenylcyclopenta-2,4-dien-1-ol have been elucidated. (1) C35H26O.CH4O is triclinic, P1BAR, a = 10.377, b = 10.778, c = 14.537 angstrom, alpha = 102.66(2), beta = 90.26(2), gamma = 117.33(2)-degrees, V = 1398(15) angstrom3, Z = 2; (II) (C35H26O)2.C2H6O is triclinic, P1BAR, a = 10.901(2), b = 13.498(2), c = 19.037(3)angstrom, alpha = 101.88(1), beta = 93.76(1), gamma = 90.84(1), V = 2734(8) angstrom3, Z = 2. The structures were refined to final residuals of 0.127 for 2207 reflections and 0.073 for 4720 reflections. Thermal analysis of the complexes confirmed the crystallographic results and gave information about their thermal decompositions.
