Abstract: In the title complex, [Cu(C18H14NO)2], the CuII ion lies on an inversion center and is coordinated in a slightly distorted square-planar environment. The 1-[(4-methylphenyl)iminomethyl]-2-naphtholate ligands are coordinated in a trans arrangement with respect to the N and O atoms.

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811010087
Abstract: In the title complex, [Ni(C18H14NO)2], the NiII ion lies on an inversion center and is coordinated in a slightly distorted square-planar environment. The 1-[(4-methylphenyl)iminomethyl]-2-naphtholate ligands are coordinated in a trans arrangement with respect to the N and O atoms. In the symmetry-unique ligand, the dihedral angle between the naphthalene ring system and the benzene ring of the methylphenyl group is 49.03 (7)°.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s160053681003374x
Abstract: In the title complex, [Cu(C18H14NO)2], the CuII ion lies on a crystallographic inversion centre and is bonded to the O- and N-donor atoms of the two bidentate chelate 1-[(o-tolyl)iminomethyl]-2-naphtholate ligands in a trans arrangement. The distorted square-planar geometry about CuII has normal dimensions, with Cu—O = 1.8881 (15) and Cu—N = 1.9804 (17) .
Bis{2,6-bis[(2-hydroxy-5-methylphenyl)iminomethyl]pyridine} monohydrate  [cached]
Muhammet Kose,Vickie McKee
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811045399
Abstract: The title compound, 2C21H19N3O2·H2O, was synthesized by a Schiff base condensation of 2,6-diformylpyridine with 2-amino-4-methylphenol in ethanol. In the crystal, two molecules of 2,6-bis[(2-hydroxy-5-methylphenyl)iminomethyl]pyridine dimerize via hydrogen bonding to a water molecule, which lies on a twofold axis. There are also intramolecular phenol–imine hydrogen bonds. The dimers are further linked via π–π (phenyl–pyridine) [centroid–centroid distance = 3.707 (2) ] and π–π edge-to-edge [3.392 (2) ] interactions. The dihedral angles between the central ring and the two pendant rings are 11.46 (8) and 2.06 (8)° while the pendant rings make a dihedral angle of 10.14 (8)°.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809007624
Abstract: In the title mononuclear copper(II) complex, [Cu(C7H5ClNO)2], the Cu atom, situated on an inversion center, is four-coordinated, in a slightly distorted square-planar geometry, by the N- and O-donor atoms of two symmetry-related 4-chloro-2-(iminomethyl)phenolate Schiff base ligands.
Bis{(E)-2-methoxy-6-[(4-methylphenyl)iminomethyl]phenolato}zinc(II)

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808033102
Abstract: The title compound, [Zn(C15H14NO2)2], contains a four-coordinate Zn atom located on a twofold rotation axis that exhibits a distorted tetrahedral geometry by two phenolate O atoms and two azomethine N atoms of the Schiff base 2-methoxy-6-[(4-methylphenyl)iminomethyl]phenolate ligands.
Bis{μ-2-[(pyridin-2-yl)iminomethyl]phenolato}bis[(2-formylphenolato)copper(II)]
Hui-Chang Chang,Jacqueline M. Cole,Tze-Chia Lin,Sven O. Sylvester
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811015674
Abstract: The asymmetric unit of the title compound, [Cu2(C12H9N2O)2(C7H5O2)2], contains two independent (2-formylphenolato){2-[(pyridin-2-yl)iminomethyl]phenolato}copper(II) molecules that form pseudocentrosymmetric dimers via interactions between the Cu and pyridyl N atoms of independent monomers. The square-planar geometry of the Cu atoms in the monomer thus becomes square-based pyramidal in the dimer. The crystal studied was an inversion twin, with unequal populations of 0.353 (17) and 0.647 (17).

Acta Crystallographica Section E , 2008, DOI: 10.1107/s160053680803417x
Abstract: In the title mononuclear copper(II) complex, [Cu(C14H9N2O)2], the CuII atom, situated on an inversion centre, shows a slightly distorted square-planar geometry and is coordinated by the N and O atoms from two deprotonated symmetry-related Schiff base ligands. The Cu—N and Cu—O bond lengths are 2.009 (2) and 1.888 (2) , respectively. The dihedral angle between the cyanophenyl rings and phenolate rings is 42.28 (13)°.
Bis{2-[(2-pyridyl)iminomethyl]phenolato}copper(II)
Jinling Miao,Zhitong Zhao,Hongwei Chen,Daqi Wang
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809026051
Abstract: In the title compound, [Cu(C12H9N2O)2], the CuII atom lies on a crystallographic inversion center and has a nearly square-planar geometry. The CuII center coordinates to the phenolic O and azomethine N atoms of the two symmetry-related 2-[(2-pyridyl)iminomethyl]phenolate ligands. The pyridyl N atoms do not coordinate to the CuII atom but participate in intramolecular C—H...N hydrogen bonding. π–π stacking between the benzene rings and between the pyridyl rings [centroid–centroid distances 3.8142 (5) and 3.8142 (5) , respectively] links the molecules into a chain propagating parallel to [100].

Abstract: In the crystal structure of the title compound, [Cu(C12H9BrN2)2](C24H20B), the copper(I) cation is coordinated by four N atoms of two crystallographically independent 2-[(4-bromophenyl)iminomethyl]pyridine ligands within a distorted tetrahedron.
