Chloridobis(2,9-diethoxy-1,10-phenanthroline-κ²N,N′)copper(II) perchlorate

X.-S. Wan, L. Meng, C.-L. Feng, C.-H. Kou and C.-Y. Niu

In the title complex, [CuCl(C₁₆H₁₆N₂O₂)₂]ClO₄, the Cu^II ion is coordinated by four N atoms from two chelating 2,9-diethoxy-1,10-phenanthroline ligands and one chloride ion in a slightly disorted trigonal-bipyramidal environment. Two N atoms and the Cl atom are in equatorial positions while the remaining two N atoms occupy apical sites, the equatorial Cu—N bonds being significantly longer than the two apical Cu—N bonds. The N=C—O—C torsion angles involving the four ethoxy groups are in the range 161.5 (8) to 177.0 (5)°. In the crystal structure, there are significant π–π stacking interactions between inversion-related rings of phenanthroline groups with centroid–centroid distances in the range 3.649 (4)–3.790 (4) Å.

Comment top

The synthesis of 2,9-Dimethoxy-1,10-phenanthroline and 2,9-diethoxy-1,10-phenanthroline have already been reported in the literature and have been shown to possess antimycoplasmal activity in the presence of copper (Pijper, et al., 1984). However, no crystal structures of their copper complexes have so far been reported. Herein we report the crystal structure of a mononuclear copper complex with 2,9-diethoxy-1,10-phenanthroline.

In the title compound, the Cu^II ion is coordinated by four nitrogen atoms from two phenanthroline rings (N1, N2, N3, N4) and one chloride ion (Cl1) forming a slightly distorted trigonal-bipyramidal geometry (Fig.1). Atoms N2, N3, and Cl1 are located in the equatorial positions and atoms N1 and N4 in the apical sites. The Cu1—N2 and Cu1—N3 bonds are significantly longer than the other two Cu—N bonds. The N=C—O—C torsion angles involving the four ethoxy groups are in the range 161.5 (8) to 177.0 (5)°. In the crystal structure, significant π···π stacking interactions between pairs of inversion related parallel rings of the phenanthroline groups give centroid-to-centroid distances in the range 3.649 (4)-3.790 (4) Å (Fig. 2). One perchlorate anion acts as the counteranion balancing the charge on the mononuclear complex.

Experimental top

2,9-diethoxy-1,10-phenanthroline was prepared according to the literature procedure (Pijper, et al., 1984). The slow evaporation of a mixture of the ligand (0.024 g, 0.1 mmol), CuCl₂ (0.016 g, 0.1 mmol), and NaClO₄^.6H₂O (0.037 g, 0.1 mmol) in 30 ml methanol afforded green block single crystals in about 15 days (yield about 70%).

Special details top

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.
