Popis:	The crystal structure of potassium dithizonate, K+[C6H5·NH·N·CS·N:NC6H5]−, has been determined by single crystal X-ray diffraction methods at 295 K and refined by full matrix least squares to a residual of 0.045 for 1101 independent “observed” reflections. Crystals are orthorhombic, Pbca, a=28.942(9), b=13.247(4), c=7.163(3)A, Z=8. The structure determination is the first carried out on a salt rather than a complex of the anion. The pseudo-planar anion stacks parallel to the ab face of the cell with considerable delocalization evident; as indicated by the above formula, the remaining acidic hydrogen atom is associated with one of the nitrogen atoms.
