Abstract

Abstract The title compound crystallizes in the centrosymmetric triclinic space group P ̄ 1 with Z= 4. The crystallographic asymmetric unit contains two independent cations; interatomic distances within these include P= O= 1.47 (1) and 1.47 (1) Å, P− C 6 H 5= 1.78 (2)–1.81 (1) Å and P− CH 2 CH 2 NMe 3+= 1.80 (1) and 1.81 (1) Å. The phosphine oxide moiety is involved in intermolecular hydrogen bonding ()... H− C, with O... H≥ 2.42 Å) and ...
