Crystal structure of 2,2''-bis-(2,7-di-chloro-9-hy-droxy-9H-fluoren-9-yl)-1,1':4',1''-terphenyl tri-ethyl-amine trisolvate.

ABSTRACT: In the title solvate, C44H26Cl4O2·3C6H15N, the asymmetric part of the unit cell comprises two halves of the diol mol-ecules, 2,2''-bis-(2,7-di-chloro-9-hy-droxy-9H-fluoren-9-yl)-1,1':4',1''-terphenyl, and three mol-ecules of tri-ethyl-amine, i. e. the diol mol-ecules are located on crystallographic symmetry centres. Two of the solvent mol-ecules are disordered over two positions [occupancy ratios of 0.567 (3):0.433 (3) and 0.503 (3):0.497 (3)]. In the diol mol-ecules, the outer rings of the 1,1':4',1''-terphenyl elements are twisted with reference to their central arene ring and the mean planes of the fluorenyl moieties are inclined with respect to the terphenyl ring to which they are connected, the latter making dihedral angles of 82.05 (8) and 82.28 (8)°. The presence of two 9-fluoren-9-
