9,9-Bis[4-(prop-2-yn-yloxy)phen-yl]-9H-fluorene.

ABSTRACT: In the title compound, C(31)H(22)O(2), the bond angle at the C atom belonging to the five-membered ring of the fluorene system is opened to 112.64?(12)°. The two benzene rings are twisted with respect to the fluorene ring system at dihedral angles of 72.81?(6) and 81.83?(6)°. One C(ar-yl)-O-C-C  fragment is extended, with a C-O-C-C torsion angle of -178.77?(13)°, but the other C(ar-yl)-O-C-C  fragment is bent, with a C-O-C-C torsion angle of 64.78?(19)°. Inter-molecular weak C-H?O hydrogen bonding is present in the crystal structure.
