Crystal structures of 3,4,5-triphenyltoluene and 3,4,5-triphenylbenzyl bromide
This article describes the crystal structures of 3,4,5-triphenyltoluene, C25H20 (1), and 3,4,5-triphenylbenzyl bromide, C25H19Br (2), which represent two intermediates of a multistep synthesis of a phenylacetic acid derivative. Compound 1 crystallizes from methanol in two polymorphic forms, with the...

| description | This article describes the crystal structures of 3,4,5-triphenyltoluene, C25H20 (1), and 3,4,5-triphenylbenzyl bromide, C25H19Br (2), which represent two intermediates of a multistep synthesis of a phenylacetic acid derivative. Compound 1 crystallizes from methanol in two polymorphic forms, with the space groups P2/n (1a) and P21/c (1b). In both cases, van der Waals forces significantly contribute to the cohesion of the crystal structure and the two polymorphs are characterized by similar modes of molecular interconnection. Compound 2 crystallizes from n-hexane in the space group P1, showing a similar pattern of noncovalent interactions to 1a and 1b. In all reported structures, the aromatic framework of the molecules adopts a paddlewheel-like conformation. |
