Abstract:	The crystal and molecular structures of the title host compound (I), C₃₅H₂₆O, and its inclusion complexes with water (II), C₃₅H₂₆O·H₂O and dimethylsulphoxide (III), C₃₅H₂₆O·C₂H₆OS are reported. (I) is monoclinicC2/c,a = 9.725(1),b = 20.031(3),c = 26.545(3) Å, = 90.60(1)⁰,V = 5170 Å³,Z = 8; (II) is triclinic, $P\bar 1$ ,a = 10.206(1),b = 10.324(2),c = 14.425(2) Å, = 101.68(1), = 89.92(2), = 116.34(1)⁰,V = 1327 Å³,Z = 2; (III) is monoclinicP2₁/n,a = 17.832(5),b = 10.109(3),c = 17.901(5) Å, = 111.93(2)⁰,V = 2993 Å³,Z =4. The structures were solved by direct methods and refined to final residuals of 0.045, 0.048, and 0.071, respectively. Thermal analysis of the complexes corroborates the crystallographic results.
