Crystal structures of bis[2-(diphenylphosphinothioyl)phenyl] ether and bis{2-[diphenyl(selanylidene)phosphanyl]phenyl} ether
The title compounds, C36H28OP2S2, (1), and C36H28OP2Se2, (2), exhibit remarkably similar structures although they are not isomorphous. The whole molecule of compound (2) is generated by twofold symmetry, with the ether O atom located on the twofold axis. Both compounds have intramolecular π–π intera...

Summary: | The title compounds, C36H28OP2S2, (1), and C36H28OP2Se2, (2), exhibit remarkably similar structures although they are not isomorphous. The whole molecule of compound (2) is generated by twofold symmetry, with the ether O atom located on the twofold axis. Both compounds have intramolecular π–π interactions between terminal phenyl rings with centroid–centroid distances of 3.6214 (16) and 3.8027 (14) Å in (1) and (2), respectively. In the crystal of (1), short C—H...S hydrogen bonds link the molecules, forming chains along [001], while in (2) there are no analogous C—H...Se interactions present. |
