In the title compound, [Ni(C(9)H(6)N(3)O(2))(2)(H(2)O)(2)], the Ni(II) atom lies on a twofold rotation axis and is six-coordinated by two bidentate chelating 4-(1,2,4-triazol-4-yl)benzoate ligands and two water mol-ecules in a distorted octa-hedral geometry. Inter-molecular O-H⋯N hydrogen bonds link the complex mol-ecules into a two-dimensional network parallel to (010).

In the title complex, [Ni(C(12)H(9)N(2)O(3)S)(2)(H(2)O)(2)]·4H(2)O, the Ni(II) ion is coordinated by four N atoms from two bidentate chelating 4-[(pyridin-2-yl)methyl-idene-amino]-benzene-sulfonate ligands and two O atoms from cis-related water mol-ecules in a slightly distorted octa-hedral environment [Ni-N = 2.071 (3)-2.121 (3) Å and Ni-O = 2.

The bidentate 1,3,4-thia-diazole ligand, namely, 2,5-bis-(2-pyrid-yl)-1,3,4-thia-diazole (denoted L), untested as a polydentate ligand, has been found to form the monomeric title complex, [Ni(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The complex shows an octa-hedral environment of the nickel cation in which the Ni(2+) ion is located on a center of symmetry, linked to two ligands and two water molecules. In this 1:2 complex (one metal for two organic ligands) each thia-diazole ligand uses one pyridyl and one thia-diazole N atom for chelate binding.

In the title complex, [Ni(C(13)H(9)N(2)O(3))(2)(H(2)O)(2)]·2H(2)O, the Ni(II) atom, located on a twofold rotation axis, is in a distorted octa-hedral geometry, defined by four N atoms from two 2-hy-droxy-5-[(pyridin-2-yl)methyl-idene-amino]-benzoate ligands and two O atoms from two water mol-ecules. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the complex mol-ecules and uncoordinated water mol-ecules into a three-dimensional network. Intra-molecular O-H⋯O hydrogen bonds are present between the hy-droxy and carboxyl-ate groups.

In the centrosymmetric title complex, [Ni(C(7)H(6)NO(2))(2)(H(2)O)(2)], the Ni(II )atom, located on an inversion center, is six-coordinated in a distorted octa-hedral geometry defined by two N and four O atoms from the two chelating 2-(2-pyrid-yl)acetate ligands and two aqua ligands. The mol-ecules form a three-dimensional framework by O-H⋯O hydrogen bonds and aromatic π-π stacking inter-actions, with a centroid-centroid distance of 3.506 (3) Å.
