(Received 23 June 2011; accepted 26 June 2011; online 30 June 2011)

The title mononuclear cobalt(III) complex, [Co(C14H19N2O2)(C8H7O2)(NCS)], was obtained by the reaction of 2-acetyl­phenol, 2-(morpholin-4-yl)ethyl­amine, ammonium thio­cyan­ate and cobalt nitrate in methanol. The CoIII atom is coordinated by one phenolate O, one imine N, and one amine N atom of the tridentate Schiff base ligand, two O atoms of the 2-acetyl­phenolate anion and one thio­cyanate N atom. This results in a fairly regular fac-CoN3O3 octa­hedral coordination geometry for the metal ion. The dihedral angle between the two benzene rings is 88.3 (3)°.

Comment top

As part of our investigations into urease inhibitors (Wang & Ye, 2011; Wang, 2009), we have synthesized the title compound, a new mononuclear cobalt(III) complex, Fig. 1. The Co atom in the complex is six-coordinated by one phenolate O, one imine N, and one amine N atoms of a Schiff base ligand 2-[1-(2-morpholin-4-ylethylimino)ethyl]phenolate, two O atoms of 2-acetylphenolate, and one thiocyanate N atom, forming an octahedral geometry. The dihedral angle between the two benzene rings are 88.3 (3) °. The three trans angles at Co atom are in the range 175.1 (1)–177.5 (1)°; the other angles are close to 90°, ranging from 84.4 (1) to 94.2 (1)° (Table 1), indicating a slightly distorted octahedral coordination. The Co–O and Co–N bond lengths (Table 1) are typical and are comparable with those observed in other similar cobalt(III) complexes (Li et al., 2007; Liu, 2010; Li et al., 2008; Wu et al., 2011).

Experimental top

2-Acetylphenol (1.0 mmol, 0.136 g), 2-morpholin-4-ylethylamine (0.5 mmol, 0.065 g), ammonium thiocyanate (1.0 mmol, 0.076 g), and cobalt nitrate hexahydrate (0.5 mmol, 0.145 g) were dissolved in MeOH (30 ml). The mixture was stirred at room temperature for 10 min to give a clear deep brown solution. After keeping the solution in air for a week, brown block-shaped crystals were formed at the bottom of the vessel.

Refinement top

All H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H distances in the range 0.93–0.97 Å, and with Uiso(H) set at 1.2Ueq(C) and 1.5Ueq(methyl C).

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.
