Abstract

The water-coordinated Zn-II atom in the title salt, [Zn-(C5H5N3O2)(2)(H2O)(2)](NO3)(2), is N,O-chelated by a zwitterionic aminopyraziniocarboxylate unit; the metal atom, which lies on a center of inversion, shows an octahedral coordination. The nitrate ion interacts indirectly, through N-H center dot center dot center dot O hydrogen bonds. In the crystal, adjacent cations and anions are connected by O-H center dot center dot center dot O hydrogen bonds into a three-dimensional network motif. The crystal studied was a non-merohedral twin with two minor components of 15.1 (1) and 8.0 (1)%.
