In the 19H20N2O4)(H2O)], there are two independent mononuclear CuII complexes. The coordination environment of each CuII ion is square-pyramidal completed by two N atoms and two O atoms forming the basal plane, and one O atom of the water molecule occupying the apical position. Neighbouring complexes are connected via O—H⋯O hydrogen bonds between the water molecule and the methoxy group, forming a chain structure along the a axis. The propylene groups of the two independent complexes are disordered over two positions with site occupancies of 0.361 (7):0.639 (7) and 0.224 (8):0.776 (8). The crystal under investigation was a partial inversion twin.

The H2L ligand was synthesized according to the previous literature (Saha et al., 2007). the synthesis method of the compound I was obtained by allowing the mixture of H2L (0.342 g, 1 mmol) and Cu(OAc)2.2H2O (0.2 g, 1 mmol) being stirred in the 10 ml methanol solution for 30 min, then filtered. The precipitation was collected and dried, the yield of the product is 0.36 g, 85%. Suitable yellow crystals were obtained via slow evaporation of the acetone solution containing this complex at room temperature
H atoms were refined using a riding model, with C—H = 0.93–0.97 Å and O—H = 0.85 Å, and with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(methyl C, O). The propylene groups of this crystal were disordered over two positions and the occupancy factors were refined to 0.361 (7):0.639 (7) and 0.224 (8):0.776 (8). The temperature factors of the unprimed and primed atoms of propylene groups have been set to equal by the 'EADP' constraint. The C—C and C—N bond lengths were restrained to 1.52 (1) and 1.50 (1) Å, respectively. The split propylene groups were refined with 'EXYZ' command to share the same C9 atom and C30 atom, respectively. The
of 0.249 (15) implies that the crystal used was a partial inversion twin.Coordination complexes have been intensively researched due to their inherent unique physical and chemical properties (Ward et al., 2007; Shankar et al., 2009). In particular, those compounds with Schiff-base ligands perform at the active sites of many metalloenzymes and therefore play important roles in biological systems (Karlin, 1993). Whereas, it appears necessary to further widen the Schiff-base system of application of metal-organic coordination compounds. Herein, a neutral mononuclear copper(II) compound has been obtained by traditional solution method and its structure is depicted in this paper.
As shown in Fig. 1, compound I is a mononuclear neutral complex [CuIIL(H2O)] with a distorted molecular configuration. Each Cu(II) ion is coordinated in a square-pyramidal geometry with the basal square built from two nitrogen atoms and two oxygen atoms from L ligand, with the apical position occupied by the water molecule. The bond lengths of Cu—O and Cu—N are normal (Sui et al., 2007). The adjacent CuL(H2O) molecules are further connected via the hydrogen bond O—H···O interaction between the coordinated water molecules and oxygen atoms of alkoxyl group, leading to a one-dimensional chain-like supramolecular structure along the a axis in Fig. 2.

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. |

Coordination complexes have been intensively researched due to their inherent unique physical and chemical properties (Ward et al., 2007; Shankar et al., 2009). In particular, those compounds with Schiff-base ligands perform at the active sites of many metalloenzymes and therefore play important roles in biological systems (Karlin, 1993). Whereas, it appears necessary to further widen the Schiff-base system of application of metal-organic coordination compounds. Herein, a neutral mononuclear copper(II) compound has been obtained by traditional solution method and its structure is depicted in this paper.
As shown in Fig. 1, compound I is a mononuclear neutral complex [CuIIL(H2O)] with a distorted molecular configuration. Each Cu(II) ion is coordinated in a square-pyramidal geometry with the basal square built from two nitrogen atoms and two oxygen atoms from L ligand, with the apical position occupied by the water molecule. The bond lengths of Cu—O and Cu—N are normal (Sui et al., 2007). The adjacent CuL(H2O) molecules are further connected via the hydrogen bond O—H···O interaction between the coordinated water molecules and oxygen atoms of alkoxyl group, leading to a one-dimensional chain-like supramolecular structure along the a axis in Fig. 2.
