The reactions of (N<sub>5</sub> )<sub>6</sub> (H<sub>3</sub> O)<sub>3</sub> (NH<sub>4</sub> )<sub>4</sub> Cl with Co(NO<sub>3</sub> )<sub>2</sub> ⋅6 H<sub>2</sub> O at room temperature yielded Co(N<sub>5</sub> )<sub>2</sub> (H<sub>2</sub> O)<sub>4</sub> ⋅4 H<sub>2</sub> O as an air-stable orange metal complex. The structure, as determined by single-crystal X-ray diffraction, has two planar cyclo-N<sub>5</sub><sup>-</sup> rings and four bound water molecules symmetrically positioned around the central metal ion. Thermal analysis demonstrated the explosive properties of the material.
