Comment top

Much interest has recently been focused on the rational design and construction of novel copper(I) complexes because of their reversible electrochemical behavior, light absorption in the visible spectral region; characteristic structural flexibility, long-lived electronically excited states, intense luminescence and ease of preparation (Armaroli, 2001; Sakaki et al., 2002). In continuation of our interests on this topic (Dehghanpour et al., 2007; Dehghanpour & Mahmoudi, 2007), we report herein the X-ray crystal structure of the copper(I) complex of the Schiff base ligand of (4-bromo-phenyl)-pyridin-2-ylmethylene-amine.

The structure of (I) consists of discrete [(C12H9BrN2)2Cu]+ cations and [BPh4]- anions (Fig. 1). The copper(I) cation centre has a tetrahedral coordination which shows signficant distortion, mainly due to the presence of the five-membered chelate ring (Table 1). The endocyclic N1—Cu—N2 angle is much smaller than the ideal tetrahedral angle of 109.5°, whereas the opposite N1—Cu—N4 angle is much wider than the ideal tetrahedral angle.

Experimental top

To a solution of (4-bromo-phenyl)-pyridin-2-ylmethylene-amine (37.8 mg, 0.1 mmol) in 20 ml acetonitrile copper tetraphenylborate (28.9 mg, 0.1 mmol)was added . The mixture was heated to dissolve the reactants, filtered off and the solvent was removed under vacuum to about 5 ml. The diffusion of diethyl ether vapor into the solution leads to light-yellow crystals. The crystals were collected and washed with diethylether. yield 83%. Calc. for C48H38BBr2CuN4: C 63.70, H 4.23, N 6.19%; found: C 63.73, H 4.21, N 6.17%.

Refinement top

All hydrogen atoms were placed in geometrically calculated positions and refined isotropic using a riding model with Uiso(H) equal to 1.2Ueq(C).

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.
