Twelve 4-(4-meth-oxy-phen-yl)piperazin-1-ium salts containing organic anions: supra-molecular assembly in one, two and three dimensions.

ABSTRACT: Twelve 4-(4-meth-oxy-phen-yl)piperazin-1-ium salts containing organic anions have been prepared and structurally characterized. The monohydrated benzoate, 4-fluoro-benzoate, 4-chloro-benzoate and 4-bromo-benzoate salts, C11H17N2O+·C7H5O2 -·H2O (I), C11H17N2O+·C7H4FO2 -·H2O (II), C11H17N2O+·C7H4ClO2 -·H2O (III), and C11H17N2O+·C7H4BrO2 -·H2O (IV), respectively, are isomorphous and all exhibit disorder in the 4-meth-oxy-phenyl unit: the components are linked by N-H⋯O and O-H⋯O hydrogen bond to form chains of rings. The unsolvated 2-hy-droxy-benzoate, pyridine-3-carboxyl-ate and 2-hy-droxy-3,5-di-nitro-benzoate salts, C11H17N2O+·C7H5O3 - (V), C11H17N2O+·C6H4NO2 - (VI) and C11H17N2O+·C7H3N2O7 - (VII), respectively, are all fully ordered: the components of (V) are linked by multiple N-H⋯O hydro
