title: Diaqua-bis-[5-(pyrazin-2-yl)-3-(pyridin-4-yl)-1H-1,2,4-triazol-1-ido-κN]zinc.
abstract: The title mononuclear complex, [Zn(C(11)H(7)N(6))(2)(H(2)O)(2)], is composed of one Zn(II) ion, two deprotonated ppt ligands [Hppt = 5-(pyrazin-2-yl)-3-(pyridin-4-yl)-1H-1,2,4-triazole] and two coordinating water mol-ecules. The asymmetric unit consists of one half-mol-ecule that is completed by application of a centre of symmetry. The Zn(II) atom is six-coordinated in an octa-hedral environment, surrounded by two O atoms in the axial positions and four N atoms in the equatorial plane. Adjacent mononuclear units are further linked via O-H⋯N hydrogen-bonding inter-actions, forming a two-dimensional network along (100).
