The title compound C17H14O, M-r = 234. 30, is orthorhombic, space group Pbc
a with unit cell of a = 16. 410 (2), b = 15. 451 (2), c = 10. 261 (2) Angst
rom, Z = 8, D-c = 1. 196 g/cm(3); V = 2601 (1) Angstrom(3); lambda(MoK alph
a) = 0. 71069 Angstrom, mu(MoK alpha) = 0. 73 cm(-1), F(000) = 992, final R
= 0. 048, R-w = 0. 053 for 1121 observed reflections with I >3. 00 sigma(I
). As the two phenyl planes and the C4H4CO group are non-coplanar,the molec
ular conjugated system was disturbed.
