A Symmetric Co(N5)2(H2O)4⋅4 H2O High-Nitrogen Compound Formed by Cobalt(II) Cation Trapping of a Cyclo-N5-Anion.
The reactions of (N5)6(H3O)3(NH4)4Cl with Co(NO3)2⋅6 H2O at room temperature yielded Co(N5)2(H2O)4⋅4 H2O as an air-stable orange metal complex. The structure, as determined by single-crystal X-ray diffraction, has two planar cyclo-N5-rings and four bound water molecules symmetrically positioned around the central metal ion. Thermal analysis demonstrated the explosive properties of the material.
