ABSTRACT: In the unsymmetrical title complex, [Ni(C(20)H(23)N(4)O(4))]ClO(4), the coordination geometry for the Ni(II) atom can be described as square planar. The aromatic rings in the two ligands are almost vertical, with a dihedral angle of 85.3°. In the crystal, cations and anions are linked by weak C(N)-H?O hydrogen bonding.

Project description:In the title mononuclear nickel(II) complex, [Ni(C(12)H(17)N(2)O(2))(NCS)], the metal atom is four-coordinated in a tetra-hedrally distorted square-planar geometry by the phenolate O atom, the imine N atom and the amine N atom of the Schiff base ligand and by the N atom of a thio-cyanate ligand. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers through inter-molecular N-H⋯O hydrogen bonds. These dimers are further connected by inter-molecular C-H⋯S hydrogen bonds, forming chains running parallel to [101].

Bis{2-formyl-4-methyl-6-[(tri-2-pyridyl-meth-yl)imino-meth-yl]phenolato}nickel(II).

Project description:The title compound, [Ni(C(25)H(19)N(4)O(2))(2)], which was obtained by the reaction of nickel(II) perchlorate with 2,6-diformyl-4-methyl-phenol and (tri-2-pyridylmeth-yl)amine in methanol solution, is a discrete monometallic complex. The Ni(II) atom is six-coordinated by the phenolate O, imine N and pyridine N atoms from two tridentate Schiff base ligands in a distorted NiN(4)O(2) octa-hedral geometry. The dihedral angles between the noncoordinated pyridyl rings of each ligand are 72.95?(8) and 69.59?(7)°.

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].

Project description:In the title compound, [Cu(C(13)H(20)N(2)O(2))(2)](ClO(4))(2), the Cu(II) atom in the complex dication is chelated by two phenolate O atoms and two imine N atoms from two zwitterionic 2-[2-(isopropyl-ammonio)ethyl-imino-meth-yl]-5-methoxy-phenolate ligands, forming a distorted square-planar geometry. One of the perchlorate anions is disordered over two sites with occupancies of 0.611?(15) and 0.389?(15). Intra-molecular N-H?O hydrogen bonds are observed in the complex dication. In the crystal structure, the perchlorate anions are linked to complex dications by inter-molecular N-H?O hydrogen bonds.
