A Symmetric Co(N-5)(2)(H2O)(4)center dot 4H(2)O High-Nitrogen Compound Formed by Cobalt(II) Cation Trapping of a Cyclo-N-5(-) Anion

摘要

The reactions of (N-5)(6)(H3O)(3)(NH4)(4)Cl with Co(NO3)(2)center dot 6H(2)O at room temperature yielded Co(N-5)(2)-(H2O)(4)center dot 4H(2)O as an air-stable orange metal complex. The structure, as determined by single-crystal X-ray diffraction, has two planar cyclo-N-5(-) rings and four bound water molecules symmetrically positioned around the central metal ion. Thermal analysis demonstrated the explosive properties of the material.
