3(pybox)]·H
2O, where pybox is 2,6-bis[(4
R)-(+)-4-isopropyl-4,5-dihydro-1,3-oxazol-2-yl]pyridine, the coordination geometry is distorted octahedral. This is the first reported complexation of the pybox molecule to a Co
III atom. The pybox ligand exhibits tridentate coordination to Co
III in a 1:1 ratio and the nitro anions occupy the remaining meridional positions of the octahedron. Molecules are linked,
via solvent water molecules, into O—H
O—N hydrogen-bonded chains.

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. |
