Abstract

Abstract The title compound crystallized in the monoclinic space group P21/c, with the following unit cell parameters: a= 11.235 (8), b= 8.473 (2), c= 26.136 (10) Å, β= 102.07 (5)°, V= 2432 (3) Å3, Z= 4.1657 unique data (Fo 2> 3 o (Fo 2)) were used to solve (direct methods) and refine the structure to give R= 0.126 and Rw= 0.118. The six-membered ring system is in a highly folded chair conformation with the phenyl group substituents on the ...
