2N,O]cobalt(III)The title compound, [Co(C10H12NO)3], was synthesized from cobalt(III) fluoride and 2-(propyliminomethyl)phenol in refluxing methanol. The CoIII ion is hexacoordinated by three N and three O atoms from three bidentate Schiff base ligands in an octahedral geometry.
A mixture of cobalt(III) fluoride (0.5 mmol) and N-n-propylsalicylaldimine (0.5 mmol) in 40 ml methanol solution was refluxed for 5 h. The filtrate from the resulting soution was allowed to evaporate at room temperature for three days. Red crystals were obtained with a yield of 21%. Anal. Calc. for C30H36CoN3O3: C 65.99, H 6.60, N 7.70%; Found: C 65.91, H 6.53, N 7.64%.
All H atoms were placed in calculated positions with C—H = 0.93Å and refined as riding with Uiso(H) = 1.2Ueq(carrier).

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. |

In recent years, Schiff base ligands have been widely used as polydentate ligands, which can coordinate to transition or rare earth ions yielding complexes with interesting properties that are useful in materials science (Church & Halvorson, 1959) and in biological systems (Okabe & Oya, 2000; Serre et al., 2005; Pocker & Fong, 1980; Scapin et al., 1997). Here we report the synthesis and X-ray crystal structure analysis of the title compound, tris(N-n-propylsalicylaldiminato)cobalt(III).
The molecular structure of the title compound is shown in Fig.1. The CoIII ion is hexacoordinated by three N and three O atoms from three bidentate Schiff base ligands, in an octahedral geometry. The Co—N and Co—O bond lengths are in the ranges 1.941 (2)–1.955 (2) and 1.8681 (19)–1.8999 (19) Å, respectively.
