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.
