5-Carboxylato-5-Hydroxy-4-(4-Methoxybenzoyl)-3-(4-Methoxyphenyl)-1,1-Dimethyl-4,5-Dihydro-1H-Pyrazol-1-Ium Monohydrate

Abstract

In the title compound, C<inf>21</inf>H<inf>22</inf>N<inf>2</inf>O <inf>6</inf>·H<inf>2</inf>O, the pyrazolium ring is in an envelope conformation. In the crystal structure, intermolecular O-H⋯O hydrogen bonds form molecular tapes along [001]. In addition, weak C-H⋯O and a C-H⋯π interaction link molecules into a three-dimensional network. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
