Acta Crystallogr C Struct Chem. 2015 Mar;71(Pt 3):239-41. doi: 10.1107/S2053229615003009. Epub 2015 Feb 21.

Abstract

Trioctylphosphine oxide (TOPO), C(24)H(51)OP, was recrystallized from ambient evaporation in acetone. TOPO single crystals form with a monoclinic P2(1)/c structure. Fourier transform IR (FT-IR) spectroscopy captures the characteristic stretching modes from the seven methylene groups, the phosphoryl P=O bond, and the phosphoryl-carbon bond.

Keywords: TOPO; crystal structure; ligand stabilizer; nanocrystal synthesis; phosphorus source; trioctylphosphine oxide.
