Comment top

As has been known for a very long time, 1,10-phenanthroline (phen) is a good bidentate chelating ligand, and has been widely introduced into the transition metal complexes. Here, we present a new six-coordinated cobalt(II) complex based on phen.

The molecular structure of the title compound is shown in Fig. 1. The coordination geometry of the Co^II ion is distorted octahedral, in which four positions are occupied by four N atoms of two chelating phen ligands and the other two occupied by two N atoms of two isocyanate ligands at a cis position. The Co—N_phen and Co—N_isocyanate bond lengths are 2.168 (2), 2.223 (3) and 2.058 (3) Å (Table 1), respectively, which are all comparable to those found in other bis(phen)cobalt(II) complexes (Cheng & Hu, 2003; He et al., 2004; Yin, 2007).

Experimental top

To a solution of 1,10-phenanthroline monohydrate (39.6 mg, 0.2 mmol) dissolved in methanol (15 ml) was added Co(ClO₄)₂.6H₂O (36.6 mg, 0.1 mmol). The mixture was stirred for 5 min before NaNCO (13 mg, 0.2 mmol) was added. After the stirring process was continued for an additional 5 min, the mixture was filtered, and the filtrate was allowed to slow evaporate to afford orange-yellow crystals suitable for X-ray diffraction with a yield about 55%.
