Crystal and molecular structure of diphenylfluoro-N-methylphosphine imide, Ph2FP:NMe

Abstract

The crystal and molecular structure of diphenylfluoro-N-methylphosphine imide has been determined by single-crystal X-ray diffraction techniques. Crystals are monoclinic with a= 8·527, b= 6·682, c= 11·346 Å, β= 106°41′ and space group P2₁. The final value of R is 4·0% for 1458 independent reflections whose intensities were measured with a diffractometer. The molecule is monomeric with a PN distance of 1·641 Å indicating the presence of d_π–p_π bonding. Other molecular parameters : mean P–C 1·806, P–F 1·488, N–C 1·469 Å F–PN 118·7, PN–C 119·1°.
