(Received 30 November 2008; accepted 8 December 2008; online 13 December 2008)

The title compound, [Co(C2H2N3)(C7H3N2O6)]n, was obtained by the reaction of CoCl2, triazole and 3,5-dinitro­benzoic acid in a 1:1:1 ratio. The Co centre is in a distorted tetrahedral coordination by three N atoms of three different triazole ligands and one O atom of the 3,5-dinitrobenzoate anion.

Supporting information


Comment top

The asymmetric unit of the title compound is shown in Fig. 1. Co is four-coordinated by one O atom of a 3,5-dinitrobenzoic acid anion and three triazole N atoms in a tetrahedral geometry. The Co—O/N bond lengths of 1.9510 (13)–2.0396 (16)Å are in the normal range. The triazole and 3,5-dinitrobenzoic acid ligands adopt tridentate and monodentate coordinating modes, respectively. As shown in Figs. 2a and 2b, cobalt ions are connected by triazole ligands to generate a two-dimensional net with the 3,5-dinitrobenzoic acid ligands stacking out of this net. There is not obvious supramolecular interaction between the two-dimensional nets.

Experimental top

CoCl2 (1.0 mmol), 3,5-dinitrobenzoic acid (1 mmol), and triazole (1 mmol) were dissolved in water (10 ml). The solution was heated in a 25 ml Teflon lined reaction vessel at 433 K for ca 3 days and then cooled to room temperature. Purple crystals were obtained in a yield of 85%.

Refinement top

All H atoms were positioned geometrically and refined using a riding model with C—H = 0.93–0.96 Å and with Uiso(H) = 1.2Ueq(C).
