R. J. Butcher, J. C. Bottaro and R. Gilardi

Abstract: The structure of the potassium salt of the dianion of 1,3,4,6-tetranitro-2,5-diazapentalene is reported, viz. 2 K⁺·C₆N₆O₈^2-. Only three atoms of the central 2,5-diazapentalene skeleton are unique, as the anion possesses 2/m symmetry. The potassium cation is nine-coordinate, forming K-O and K-N bonds to five different 1,3,4,6-tetranitro-2,5-diazapentalene anions.
