Bis(2-imino-methyl-5-methoxy-phenolato)nickel(II).

Project description:The title compound, [Ni(C(8)H(8)NO(2))(2)], is a centrosymmetric mononuclear nickel(II) complex. The Ni(II) ion, lying on an inversion centre, is four-coordinated in a square-planar geometry by two phenolate O and two imine N atoms from two symmetry-related 2-imino-methyl-5-methoxy-phenolate ligands. In the crystal, mol-ecules are linked into corrugated layers parallel to (100) by N-H?O hydrogen bonds.

Bis(2-hydroxy-imino-methyl-6-methoxy-phenolato-?O,N)cobalt(II).

Project description:In the title compound, [Co(C(8)H(8)NO(3))(2)], the Co(II) atom lies on a centre of inversion and is coordinated in a slightly distorted square-planar geometry by two N and two O atoms from the 2-hydroxy-imino-methyl-6-methoxy-phenolate ligands. Intra-molecular O-H?O hydrogen bonds are formed and the complexes form stacks along the b axis, with an inter-planar separation of 3.332?(1)?Å between complexes. Pairs of C-H?O contacts are formed between complexes in neighbouring stacks.

Bis{2-[2-(isopropyl-ammonio)ethyl-imino-meth-yl]-6-methoxy-phenolato}nickel(II) dithio-cyanate.

Project description:The title complex, [Ni(C(13)H(20)N(2)O(2))(2)](NCS)(2), consists of a centrosymmetric mononuclear four-coordinate nickel(II) complex cation and two thio-cyanate anions. The Ni atom is located on an inversion center and is coordinated by two phenol O atoms and two imine N atoms from two equivalent Schiff base ligands, in a square-planar geometry. In the crystal structure, the amino H atoms are involved in N-H⋯O hydrogen bonds with the phenol and meth-oxy O atoms of the ligand, and in N-H⋯N hydrogen bonds with the N atoms of the thio-cyanate anions, which sit above and below the Ni atom.

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.

The dihedral angle between the cyano-phenyl and phenolate rings is 47.62?(7)°.

Bis[2-(1-imino-eth-yl)phenolato-?N,O]nickel(II).

Project description:There are one and a half independent mol-ecules in the asymmetric unit of the title compound, [Ni(C(8)H(8)NO)(2)], one of which is situated on an inversion center. In both mol-ecules, the Ni(II) ion is coordinated by two O and two N atoms from two Schiff base ligands in an approximate square-planar geometry. Inter-molecular N-H?O hydrogen bonds link three mol-ecules into centrosymmetric trimer. The crystal packing exhibits weak inter-molecular C-H?O hydrogen bonds and voids of 37?Å(3).
