Descripción
Sumario:The water-coordinated Zn(II) atom in the title salt, [Zn(C(5)H(5)N(3)O(2))(2)(H(2)O)(2)](NO(3))(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⋯O hydrogen bonds. In the crystal, adjacent cations and anions are connected by O—H⋯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)%.
