In the title complex, [Ni(C(9)H(9)BrNO)(2)], the Ni(II) ion lies on an inversion centre and is coordinated in a slightly distorted square-planar geometry by two N atoms and two O atoms from two symmetry-related bidentate 4-bromo-2-(ethyl-imino-meth-yl)phenolate ligands. The complex forms a one-dimensional chain in the crystal structure through short C-H⋯Br contacts (H⋯Br = 3.009 Å).

The unit cell of the title compound, [Ni(CHClN)]·2CHOH, consists of a neutral complex and two methanol mol-ecules. In the complex, the two tridentate 2-(3-(4-chloro-phen-yl)-1-1,2,4-triazol-5-yl)-6-(1-pyrazol-1-yl)pyridine ligands coordinate to the central Ni ion through the N atoms of the pyrazole, pyridine and triazole groups, forming a pseudo-octa-hedral coordination sphere. Neighbouring tapered mol-ecules are linked through weak C-H(pz)⋯π(ph) inter-actions into monoperiodic chains, which are further linked through weak C-H⋯N/C inter-actions into diperiodic layers.

In the title complex, [Ni(CHN)](CFSO)·(CHCH)O, the central Ni atom is sixfold coordinated by three nitro-gen atoms of each 2,6-bis-(2-benzimidazol-yl)pyridine ligand in a distorted octa-hedral geometry with two tri-fluoro-methane-sulfonate ions and a mol-ecule of diethyl ether completing the outer coordination sphere of the complex. Hydrogen bonding contributes to the organization of the asymmetric units in columns along the axis generating a porous supra-molecular structure. The structure was refined as a two-component twin with a refined BASF value of 0.

The reaction of -phenyl-enedi-amine (OPD), sodium naphthalene1,5-di-sulfonate (NaNDS) and nickel sulfate in an ethanol-water mixture yielded the title compound, [Ni(OPD)(HO)]·NDS or [Ni(CHN)(HO)](CHOS). This salt consists of a complex [Ni(OPD)(HO)] cation with two bidentate OPD ligands and aqua ligands, and a non-coordinating NDS anion, which is the double-deprotonated form of HNDS. The Ni atom is situated at a center of inversion and exhibits a slightly tetra-gonally distorted {ON} octa-hedral coordination environment, with four shorter equatorial Ni-N bonds [2.
