4-(2-Meth-oxy-phen-yl)piperazin-1-ium 6-chloro-5-isopropyl-2,4-dioxopyrimidin-1-ide.

ABSTRACT: In the cation of the title salt, C11H17N2O(+)·C7H8ClN2O2 (-), the piperazine ring adopts a distorted chair conformation and contains a positively charged N atom with quaternary character. Its mean plane makes a dihedral angle of 42.36?(8)° with the phenyl ring of its 2-meth-oxy-phenyl substituent. The 2,4-dioxopyrimidin-1-ide anion is generated by deprotonation of the N atom at the 1-position of the pyrimidine-dione ring. Intra-molecular C-H?O hydrogen bonds generate S(6) ring motifs in both the cation and the anion. In the crystal, N-H?O, N-H?N and C-H?O hydrogen bonds are also observed, resulting in a two-dimensional network parallel to the ab plane. The crystal stability is further consolidated by weak C-H?? inter-actions.
