ABSTRACT: In the title compound, [Ni(C(13)H(11)ClN(3)O(2))(2)], the Ni(II) atom is located on a twofold rotation axis and is six-coordinated by four N atoms and two phenolate O atoms from the two equal Schiff base ligands in a distorted octa-hedral coordination geometry. The complex mol-ecules are connected by C-H?Cl, C-H?O and N-H?O hydrogen bonds.

Redetermination of bis-(2-formyl-phenolato-κO,O')nickel(II) as bis-[2-(imino-meth-yl)phenolato-κN,O']nickel(II).

Project description:The crystal structure of bis-(2-formyl-phenolato-κ(2)O,O')nickel(II), [Ni(C(7)H(5)O(2))(2)], a square-planar centrosymmetric complex, has been reported previously [Li & Chen (2006). Acta Cryst. E62, m1038-m1039]. However, a number of warning signs allows the assumption that the carbonyl group in the salicylaldehydate ligand of the claimed complex is incorrect. The crystal structure was therefore redetermined on basis of the originally deposited structure factors. After substituting the carbonyl O atom by an N atom, the model can be completed with an imine H atom, which was clearly discernible in a difference map. The resulting model, corresponding to bis-[2-(imino-meth-yl)phenolato-κ(2)N,O']nickel(II), [Ni(C(7)H(6)NO)(2)], converges well and none of the previous structural alerts remains. This reinter-pretation is also consistent with the published synthesis, which was carried out using salicylaldehyde in the presence of aqueous NH(3). The reinter-preted structure is virtually identical to earlier reports dealing with this bis-iminato Ni(II) complex.

Bis[2-(benzyl-amino)-pyridine-κN]bis-(2-formyl-phenolato-κO,O')nickel(II).

Project description:In the title complex, [Ni(C(7)H(5)O(2))(2)(C(12)H(12)N(2))(2)], the Ni(II) atom lies on a center of inversion and is coordinated in an octa-hedral geometry by two 2-(benzyl-amino)-pyridine (2-BAP) and two 2-formyl-phenolate ligands with the O-atom donors in the equatorial plane and the pyridine N atoms in axial positions. There are hydrogen-bonding inter-actions between the secondary amine H atom and the phenolate O atom, as well as C-H⋯O inter-actions, which result in the dihedral angle between the aromatic phenyl ring of the 2-formyl-phenolate moiety and the pyridine ring being 80.23 (4)°. In the packing, there are both C-H⋯π inter-actions, which link the mol-ecules into chains along the b axis, and offset π-π inter-actions involving both the pyridine and phenyl rings of the 2-BAP ligands [centroid-centroid distances = 4.0100 (8) Å for the pyridine rings and 3.6601 (8) and 4.8561 (8) Å for the phenyl rings].

Bis[bis-(2-ethyl-5-methyl-1H-imidazol-4-yl-κN)methane](nitrato-κO,O')nickel(II) nitrate.

Project description:In the title compound, [Ni(NO(3))(C(13)H(20)N(4))(2)]NO(3), the Ni(II) ion shows a distorted octa-hedral geometry formed by four N atoms from two bis-(2-ethyl-5-methyl-1H-imidazol-4-yl)methane ligands and two O atoms from a chelating nitrate anion. Three ethyl groups in the complex cation and the O atoms of the uncoordinated nitrate anion are disordered over two sets of positions [occupancy ratios of 0.52 (3):0.48 (3) and 0.63 (3):0.37 (3), respectively]. In the crystal, inter-molecular N-H⋯O hydrogen bonds connect the complex cations into a zigzag chain along [010] and further N-H⋯O hydrogen bonds between the chains and the uncoordinated nitrate anions lead to layers parallel to (100).
