چکیده
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-formylphenolato-κ2 O,O′)nickel(II) as bis[2-(iminomethyl)phenolato-κ2 N,O′]nickel(II)
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 therefor...

In the solvated title complex, [Ni(C(46)H(47)N(6)O(2))]ClO(4)·2CH(4)O, the coordination sphere around the Ni(II) ion can be described as distorted cis-NiO(2)N(4) octa-hedral defined by two phenolate O atoms and four N atoms from the hexa-dentate ligand. An intra-molecular bifurcated N-H⋯(N,O) hydrogen bond helps to establish the conformation of the complex mol-ecule. In the crystal, the compone...
