For their biological activity, see: Brückner et al. (2000); Harrop et al. (2003); Ren et al. (2002). For polynuclear complexes involving bridging ligands, see: Salem (2005); Dohlakiya & Patel (2005); Dey et al. (2004). For a related structure, see: Diao (2007).
2-Hydroxy-3-methoxybenzaldehyde (0.2 mmol, 30.5 mg), N,N-dimethylethane-1,2-diamine (0.2 mmol, 17.5 mg), NaN3 (0.2 mmol, 13.0 mg), and Cu(CH3COO)2.H2O (0.2 mmol, 40.0 mg) were dissolved in an 95% ethanol solution (30 ml). The mixture was stirred at room temperature for 30 min to give a deep blue solution. After keeping the solution in air for a few days, deep blue crystals were formed.
The crystals were very weakly diffracting and few high angle reflections were obtained. This explains the low measured fraction of data in this determination. Water H atoms were located from a difference Fourier map and refined isotropically. All other H atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.93 Å, Uiso = 1.2Ueq (C) for aromatic, 0.97 Å, Uiso = 1.2Ueq (C) for CH2 and 0.96 Å, Uiso = 1.5Ueq (C) for CH3 atoms.
Polynuclear complexes play an important role in the development of coordination chemistry (Eshel et al., 2000; Jiang et al., 2005; Escuer et al., 2000; El-Behairy et al., 1997; Manhas et al., 2005). Some of the complexes have been found to have pharmacological and antitumor properties (Brückner et al., 2000; Harrop et al., 2003; Ren et al., 2002). A prime strategy for designing these molecular materials is to use suitable bridging ligands (Salem, 2005; Dohlakiya & Patel, 2005; Dey et al., 2004). The azide ligand displays a number of coordination modes and has become one of the most extensively studied building blocks in the field. We recently reported the structure of an azide-bridged polynuclear copper(II) complex (Diao, 2007) and we report herein the crystal structure of the related title complex (I), Fig 1.
The complex is an azide-bridged dinuclear copper(II) complex. One Cu atom is six-coordinated by the phenolic O atom, one imine, and one amine N atoms from one Schiff base ligand, the phenolic and ether O atoms of the second Schiff base, together with a terminal N atom of the bridging azide ligand, in an octahedral geometry. The coordination sphere of the second Cu atom contains a phenolic O, imine and amine N atoms from one Schiff base ligand, two N atoms one from the bridging and the other from a terminal azide ligand, and a coordinated water molecule, also in an octahedral geometry.

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. |

Polynuclear complexes play an important role in the development of coordination chemistry (Eshel et al., 2000; Jiang et al., 2005; Escuer et al., 2000; El-Behairy et al., 1997; Manhas et al., 2005). Some of the complexes have been found to have pharmacological and antitumor properties (Brückner et al., 2000; Harrop et al., 2003; Ren et al., 2002). A prime strategy for designing these molecular materials is to use suitable bridging ligands (Salem, 2005; Dohlakiya & Patel, 2005; Dey et al., 2004). The azide ligand displays a number of coordination modes and has become one of the most extensively studied building blocks in the field. We recently reported the structure of an azide-bridged polynuclear copper(II) complex (Diao, 2007) and we report herein the crystal structure of the related title complex (I), Fig 1.
The complex is an azide-bridged dinuclear copper(II) complex. One Cu atom is six-coordinated by the phenolic O atom, one imine, and one amine N atoms from one Schiff base ligand, the phenolic and ether O atoms of the second Schiff base, together with a terminal N atom of the bridging azide ligand, in an octahedral geometry. The coordination sphere of the second Cu atom contains a phenolic O, imine and amine N atoms from one Schiff base ligand, two N atoms one from the bridging and the other from a terminal azide ligand, and a coordinated water molecule, also in an octahedral geometry.
