Sa. Mitchenko et al., Generation of platinum(III) species by mechanical treatment of solid K2PtX6 (X = Cl, Br) salts, MENDELEEV C, (5), 1999, pp. 171-172A
A mechanical treatment of the solid salts K2PtX6 containing a small admixtu
re of K2PtX4 (X = Cl, Br) in the atmosphere of air or argon leads to the fo
rmations of paramagnetic platinum d(7)-complexes.
