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 amino-pyraziniocarboxyl-ate unit; the metal atom, which lies on a center of inversion, shows an octa-hedral coordination. The nitrate ion inter-acts 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 tw ...[more]
