Guanidinum diphenylphosphinate monohydrate

Abstract

Hydrogen bonding in the title structure, CH6N3+·C12H10O2P-H 2O or [C(NH2)3]+[Ph 2PO2]-·H2O, results in a bilayer architecture, which also involves π-π stacking interactions between pairs of guanidinium ions. All the cation H atoms are involved in hydrogen bonds, five to O atoms of the anion or solvent water and the sixth in an N - H⋯π interaction with a neighbouring phenyl ring. © 2006 International Union of Crystallography All rights reserved.
