In the crystal structure of the title compound, [Co(C₂H₄NO₂)(C₉H₆NO)₂]·CH₃OH, the Co^III atom is chelated by two quinolin-8-olate and one glycinate anions in a distorted octahedral coordination geometry. The five-membered chelating glycinate ring assumes an envelope conformation. The complex molecules are assembled by intermolecular N—H⋯O hydrogen bonding.

Comment top

The 8–hydroxyquinoline (HQ) is a very good ligand, forms complex compounds with various metal ions in solution. The strong chelating action of HQ in solution has been extensively studied and widely used in analytical chemistry. In this work, we use glycin and 8–hydroxyquinoline as bidedtate ligand to synthesize the title complex, (I).

The molecular structure of the title compound is shown in Fig. 1. The Co^III atom is chelated by two 8-hydroxyquinoline and one glycin anions in a distorted octahedral coordination geometry. The Co—N bond distances are longer than Co—O bond distances (Table 1), which agrees with that found in a related structure, tris(8-quinolinolato)-cobalt(III) methanol solvate (Li et al. 2003). The two 8-hydroxyquinolate rings are almost perpendicular to each other with a dihedral angle of 81.0°. The five-membered chelating ring of the glycin assumes an envelope conformation, with N3 atom at the flap position. The complex molecules are assembled by intermolecular N–H···O hydrogen bonding (Table 2). Lattice methanol molecule is linked with complex via O—H···O and N—H···O hydrogen bonding (Fig. 2).

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.
