(2,2′-Bipyridine)(2-formyl-6-methoxyphenolato)nickel(II) perchlorate

C.-J. Wang, P.-D. Ren, W.-P. Wu and Z.-B. Zhang

In the title compound, [Ni(C₈H₇O₃)(C₁₀H₈N₂)]ClO₄, the Ni^II atom is in a slightly distorted square-planar coordination by two N atoms from the 2,2′-bipyridine (bipy) ligand and two O atoms from the deprotonated 2-formyl-6-methoxyphenolate (mbd) ligand. The bipy ligand is nearly coplanar with the Ni^II square plane, the Ni atom being only 0.042 (2) Å from the mean plane, whereas the benzaldehyde plane is folded with respect to the square plane, making a dihedral angle of 19.17 (8)°. One of the O atoms of the perchlorate anion is involved in a weak interaction with the Ni atom, with an Ni—O distance of 2.5732 (18) Å. The packing is stabilized by weak C—H

O interactions.

Comment top

2,2'-Bipyridyl ligand is bidentate chelating ligand, which can commonly act as terminal ligands, and may also provide molecular interaction sites for molecular recognition or assembly (Minuti et al., 1999; Hamblin et al., 2002). On the other hand, aldehyde ligands have significant importance in chemistry, specially in the development of its complexes, because this type ligands are potentially capable of forming stable complexes with metal ions (Alizadeh et al., 1999). Herein we report the synthesis and characterization of the title complex with mixed co-ligand.

The Ni^II atom in the title complex, has a square coordination formed by two N atoms from Bipy ligand and two O atoms from protonated mbd ligand (Fig. 1). One of the O atom of the perchlorate anion is in weak interaction with the Ni atom with a Ni—O distance of 2.5732 (18) Å. The average Ni—N bond length of 1.98 Å is close to the values observed in related complexes (Liu et al., 2008). The occurrence of C—H···O hydrogen bonding stabilizes the packing (Table 1).

Special details top

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.
