In the title compound, [Cu(C8H7O2)(NO3)(C10H8N2)], the CuII ion is five-coordinate in a distorted square-pyramidal geometry. The basal positions are occupied by two N atoms from a 2,2′-bipyridine ligand and two O atoms from the 2-acetylphenolate anion. The axial position is occupied by one O atom of a nitrate anion. In the bipyridine ligand, the two pyridine rings are slightly twisted by an angle of 3.5 (1)°. The is stabilized by C—H⋯O hydrogen bonds

The crystal used in this
was obtained adventitiously from an attempted preparation of a copper(II)-Schiff base complex. It was synthesized as described in the literature (Plesch et al., 1997). 2-Hydroxyacetophenone (1.00 mmol) in methanol (10 ml) was added dropwise to a soltion of beta-alaine (1.00 mmol) and potassium hydroxide (1.00 mmol) in methanol (10 ml). The yellow solution was stirred for 2 h at 333 K. The resultant mixture was added dropwise to copper(II) nitrate trihydrate (1.00 mmol) and 2,2'-bipyridine (1.00 mmol) in an aqueous methanolic solution (20 ml, 1:1 v/v), and heated with stirring for 2 h at 333 K. The dark blue solution obtained was filtered and left for several days; dark blue crystals were formed which were filtered off, washed with water, and dried under vacuum.H atoms were positioned geometrically and refined as riding, with C-H = 0.93 (CH) or 0.96 Å (CH3) and Uiso(H) = xUeq(C,N), where x = 1.5 for methyl H atoms and 1.2 for other H atoms.

We report here the
of the title CuII complex.In the title compound, the CuII ion is in a distorted square-pyramidal geometry (Fig. 1 and Table 1). The four basal positions are occupied by two N donor atoms from a 2,2'-bipyridine ligand and two O atoms from the 2-acetylphenolate anion. The axial position is occupied by one O atom of a nitrate anion. The Cu1 atom is displaced from the O1/O2/N1/N2 basal plane toward the O3 atom by 0.1472 (3) Å. In the pipyridine ligand, the two pyridine rings are twisted slightly by an angle of 3.5 (1)°. The N1- and N2-pyridine rings form dihedral angles of 16.2 (1) and 15.6 (1)°, respectively, with the benzene ring.
The
is stabilized by C—H···O hydrogen bonds (Table 2).For related structures, see: Bevan et al. (1963); Falguni et al. (1998); Garland et al. (1986); Gasque et al. (1999); Ming et al. (1995); Reki et al. (1998); Solans et al. (1987). For the synthesis, see: Plesch et al. (1997).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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. |

We report here the crystal structure of the title CuII complex.
In the title compound, the CuII ion is in a distorted square-pyramidal geometry (Fig. 1 and Table 1). The four basal positions are occupied by two N donor atoms from a 2,2'-bipyridine ligand and two O atoms from the 2-acetylphenolate anion. The axial position is occupied by one O atom of a nitrate anion. The Cu1 atom is displaced from the O1/O2/N1/N2 basal plane toward the O3 atom by 0.1472 (3) Å. In the pipyridine ligand, the two pyridine rings are twisted slightly by an angle of 3.5 (1)°. The N1- and N2-pyridine rings form dihedral angles of 16.2 (1) and 15.6 (1)°, respectively, with the benzene ring.
The crystal structure is stabilized by C—H···O hydrogen bonds (Table 2).
