The title complex, [Co(C10H6NO2)2(CH4O)2], is a neutral mononuclear complex containing a CoII ion in a six-coordinate environment. The CoII center, located on a crystallographic center of symmetry, displays a slightly distorted octa­hedral geometry, with two quinoline-8-carboxyl­ate and two methanol ligands in trans configurations. The complex mol­ecules are linked together by O—H...O and C—H...O hydrogen bonds between methanol mol­ecules and carboxyl­ate groups to form a three-dimensional framework.

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.
