The tetradentate dianion in the title complex hydrate, [Cu(C23H28N2O4)]·H2O, provides the CuII atom with a cis-N2O2 donor set. There is a significant twist from a regular square-planar geometry with the dihedral angle formed between the two six-membered CuOC3N chelate rings being 32.14 (8)°. The water molecule forms hydrogen bonds to each of the coordinating O atoms of a given complex molecule. Supramolecular layers in the bc plane are formed in the crystal packing through C—H⋯O and C—H⋯π interactions.

The title complex was obtained by the template method in a branch tube (Harrowfield et al., 1996). The recently described (Ghaemi et al., 2011) N,N'-bis(2-hydroxy-4-methoxyacetophenone)-2,2-dimethylpropane-1,3-diamine (0.40 g, 1 mmol) and copper(II) acetate monohydrate (0.199 g, 1 mmol) were placed in the main arm of a branched tube. Ethanol was added to fill both arms. The tube was sealed and the main arm immersed in an oil bath at 333 K while the other was held at ambient temperature. After one week, crystals deposited in the cooler arm. These were filtered off and air dried. Yield: 75%. FT—IR data: ν(C═N) 1595 cm-1.
The H-atoms were placed in calculated positions (C—H 0.93 to 0.97 Å) and were included in the
in the riding model approximation, with Uiso(H) set to 1.2 to 1.5Uequiv(C). The water-H atoms were placed in calculated positions (O—H = 0.84 Å; 1.5Uequiv(O) on the basis of hydrogen bonding.Synthetic copper(II) Schiff base complexes have long been of great interest because of their potential as catalysts in the oxidation of various organic compounds (Gupta & Sutar, 2008). In continuation of research in this field (Rayati et al., 2010), the title complex, (I), was investigated.
The tetradentate dianion in the title monohydrate, (I), Fig. 1, provides a cis-N2O2 donor set, Table 1. Three six-membered chelate rings are formed as a result of coordination of the dianion. The CuNC3N ring adopts a half-chair conformation. While the CuOC3N chelate ring containing the O3 atom approaches planarity with a r.m.s. deviation of 0.031 Å, the other ring displays significant distortions. Thus, the r.m.s. deviation for the O2-containing CuOC3N chelate ring is 0.163 Å with maximum deviations of 0.162 (2) Å for atom O2 and -0.159 (1) Å for the Cu atom. The dihedral angle formed between the two CuOC3N chelate rings is 32.14 (8)° indicating a significant distortion from a regular square planar geometry. Each of the methoxy groups is co-planar with the benzene ring to which it is attached as seen in the values of the C7—O1—C3—C2 and C23—O4—C20—C19 of -0.8 (4) and -179.3 (3)°, respectively. The water molecule of solvation is associated with the complex, forming a bridge via its hydrogen atoms between the two coordinated oxygen atoms, Table 2.
The crystal packing features C—H···O and C—H···π interactions, Table 2, that assemble molecules into layers in the bc plane, Fig. 2, which stack along the a axis, Fig. 3.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Synthetic copper(II) Schiff base complexes have long been of great interest because of their potential as catalysts in the oxidation of various organic compounds (Gupta & Sutar, 2008). In continuation of research in this field (Rayati et al., 2010), the title complex, (I), was investigated.
The tetradentate dianion in the title monohydrate, (I), Fig. 1, provides a cis-N2O2 donor set, Table 1. Three six-membered chelate rings are formed as a result of coordination of the dianion. The CuNC3N ring adopts a half-chair conformation. While the CuOC3N chelate ring containing the O3 atom approaches planarity with a r.m.s. deviation of 0.031 Å, the other ring displays significant distortions. Thus, the r.m.s. deviation for the O2-containing CuOC3N chelate ring is 0.163 Å with maximum deviations of 0.162 (2) Å for atom O2 and -0.159 (1) Å for the Cu atom. The dihedral angle formed between the two CuOC3N chelate rings is 32.14 (8)° indicating a significant distortion from a regular square planar geometry. Each of the methoxy groups is co-planar with the benzene ring to which it is attached as seen in the values of the C7—O1—C3—C2 and C23—O4—C20—C19 of -0.8 (4) and -179.3 (3)°, respectively. The water molecule of solvation is associated with the complex, forming a bridge via its hydrogen atoms between the two coordinated oxygen atoms, Table 2.
The crystal packing features C—H···O and C—H···π interactions, Table 2, that assemble molecules into layers in the bc plane, Fig. 2, which stack along the a axis, Fig. 3.
