The polyanion P 3 4⊖in K 4 P 3 is isoelectronic and isostructural with O 3 ⊖and ClO 2 ; it is a radical anion with 19 valence electrons. The magnetism indicates presence of a system with three unpaired electrons. K 4 P 3 is obtained in the form of bluish‐black platelets having a metallic luster, which decompose explosively on rubbing. The structure of K 4 P 3 is characterized by angular P 3 chains and condensed trigonal K prisms (see figure on the right).
