The Secondary Explosive Tetraammine-cis-bis(5-nitro-2H-tetrazolato-N²)cobalt(III) Perchlorate at 293 and 213 K

For the title compound, (OC-6-22)-[Co(CN₅O₂)₂(NH₃)₄]ClO₄, the structure determination confirms the cis relationship of the two ring ligands deduced from NMR and shows that these ligands involve N-2 bonding to the Co atom. The accompanying low temperature study suggests several O atoms of the ClO₄^- ion are slightly disordered rather than having large thermal displacements.
