In the title complex, [Ni(C(20)H(10)Br(2)Cl(2)N(2)O(2))], the Ni(II) ion is coordinated by two phen-oxy O atoms and two imino N atoms of the tetradentate ligand, forming a slightly distorted square-planar environment. The mol-ecule is essentially planar, with an r.m.s. deviation of 0.088 Å for the mean plane defined by all non-H atoms in the mol-ecule.

In the title compound, [Ni(CHBrNO)], the Ni ion is four-coordinated in a slightly distorted square-planar coordination geometry defined by two N atoms and two O atoms of the tetra-dentate dianionic 4,4'-di-bromo-2,2'-[cyclo-hexane-1,2-diylbis(nitrilo-methanylyl-idene)]diphenolato ligand. Pairs of complex mol-ecules are assembled by inter-molecular C-H⋯O hydrogen bonds with (C⋯O) = 3.247 (4) Å.

In the title complex, [Ni(C17H16N2O5)]·2H2O, the Ni(II) ion is four-coordinated by two azomethine N and two phenolato O atoms of the tetradentate Schiff base ligand in a slightly distorted square-planar geometry. In the six-membered ring containing the metal, the azomethine N atoms and the three C atoms of the connecting 1,3-di-amino-propane-2-ol, all atoms except the metal are disordered over two sets of sites with an occupacy ratio of 0.566 (3):0.

In the mol-ecule of the title compound, [Ni(C19H20N2O4)(H2O)2], the central Ni(II) ion lies on a mirror plane and is surrounded by an N2O4 coordination set in the form of a distorted octa-hedron defined by the O atoms of two water mol-ecules and by two phenolic O and two imine N atoms of the tetra-dentate Schiff base ligand. In the crystal, O-H⋯O hydrogen bonds between the water mol-ecules and the phenolic and meth-oxy O atoms of neighbouring mol-ecules lead to the formation of rods propagating parallel to [100].

The asymmetric unit of the title compound, [Ni(C(17)H(12)I(4)N(2)O(2))], comprises half of a Schiff base complex. The Ni(II) and central C atom of the propyl chain are located on a twofold rotation axis. The geometry around the Ni(II) atom is square planar, supported by the N(2)O(2) donor atoms of the coordinated ligand.
