title: Diaqua-bis-[5-(pyrazin-2-yl-κN)-3-(pyridin-3-yl)-1,2,4-triazolido-κN]cadmium.
abstract: In the title compound, [Cd(C(11)H(7)N(6))(2)(H(2)O)(2)], the Cd(II) cation is located on an inversion center and is coordinated by four N atoms from two 5-(pyrazin-2-yl)-3-(pyridin-3-yl)-1,2,4-triazol-ide anions and two water mol-ecules in a distorted octa-hedral geometry. The triazolide ligand is nearly planar: the central triazole ring is oriented at dihedral angles of 4.63 (13) and 8.41 (13)° with respect to the pyrazine and pyridine rings. Inter-molecular O-H⋯N hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular network parallel to (001).
