The reactions of (N 5 ) 6 (H 3 O) 3 (NH 4 ) 4 Cl with Co(NO 3 ) 2 ⋅6 H 2 O at room temperature yielded Co(N 5 ) 2 (H 2 O) 4 ⋅4 H 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.
