Abstract

The interaction between water and phosphine isolated in solid argon matrices has been investigated. Infrared spectra of matrices containing water and phosphine, as well as their deuterium and ¹⁸O isotopologues, revealed that a weak hydrogen bonded complex is formed, with an O–H⋯P bonding motif. This was supported by high level ab initio calculations, which predict a binding energy of only 5.1 kJ mol⁻¹ (430 cm⁻¹).
