Deprotonation of phenol by tetra-n-butylammonium hydroxide and subsequent removal of water by P2O5 results in quantitative formation of tetra-n-butylammonium phenol-phenolate. The compound crystallizes as an ion pair, with the solute phenol molecule intimately attached to the phenolate anion by an O-H?O- hydrogen bond (O?O 2.471(5)?). A short contact between one α-C atom of the tetra-n-butylammonium cation and the phenolate O atom indicates that the ion pair interaction is strengthened by an additional C-H?O- hydrogen-bond, despite the attached phenol.
