In the mononuclear title complex, [Co(C₁₁H₁₇N₄O₂)₂(CH₃OH)₂](ClO₄)₂, the cobalt(II) atom lies on a symmetry centre and is coordinated by two O,N-bidentate ligands and two trans-arranged O atoms of the methanol molecules in a slightly distorted octahedral geometry. In the crystal structure, cations and anions are linked by N—H⋯O and O—H⋯O hydrogen bonds into layers parallel to the bc plane.

Comment top

Engineering of molecular magnets constitutes a major research goal and has spawned interest in organic radicals as building blocks for construction of new materials (Marvilliers et al., 1999; Yamamoto et al., 2001). In this field, nitronyl nitroxides acting as useful paramagnetic building blocks have been extensively used to assemble molecular magnetic materials, because many of them are good stable spin carriers even when coordinated to metal ions. Various substitutions on radical ligands can lead to large change in not only coordination modes but also electronic behaviours, so a large number of investigations on various properties of metal-radicals complexes have been carried out and aroused intense interest and far-ranging studies (Chang et al., 2009; Zhang et al., 2007; Omata et al., 2001; Fokin et al., 2004; Wang et al., 2005). In this article, we report the synthesis and crystal structure of a novel cobalt(II) complex with the nitronyl nitroxide radical.

The crystal structure of the title compound is shown in Figure. 1. The cobalt(II) ion lies on a symmetry centre and is six-coordinate in a slightly distorted octahedral CoN₄O₂ environment provided by two O,N-bidentate ligands and two trans-arranged oxygen atoms of methanol molecules. The Co1/O1/N3/C4/C1/N1 six-membered chelatating ring assumes a half-boat conformation, with atoms O1 and C1 displaced by 0.402 (3) and 0.195 (3) Å, respectively, from the mean plane of the other atoms. In the crystal structure, cations and anions are linked by N—H···O and O—H···O hydrogen bonds (Table 1) into layers parallel to the bc plane.

Experimental top

The nitronyl nitroxide radical (4,4,5,5-tetramethyl-2-(5-methylimidazol-4-yl)-2-imidazoline-1-oxyl-3-oxide) was synthesized according to the literature procedures (Ullman et al., 1970; Ullman et al., 1972). The complex was synthesized by mixing 5 ml of a methanol solution of nitronyl nitroxide radical (0.4 mmol) and 5 ml of a methanol solution of Co(ClO₄)₂.6H₂O (0.2 mmol). After stirring for two hours at room temperature, the mixture solution was filtered. The clear deep purple filtrate was diffused with diethyl ether vapour at room temperature for two days, to afford deep purple crystals suitable for X-ray analysis.

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.
