Studies on potassium tri-µ-nitro-µ3-oxo-cyclo-tris[nitroplatinate(II)] trihydrate, Vèzes' red salt

Abstract
A new investigation of Vèzes' red salt, first prepared in 1893 indicates that it should be reformulated as K2[Pt3(NO2)6O]·3H2O. Analytical, infrared, X-ray, and electrical-conductivity evidence suggests that the structure of the compound consists of planar anions arranged in a columnar stack resulting in the formation of linear chains of platinum atoms.
