Determination of interatomic distances of statistically oriented OsO₃N⁻ in potassium nitridoosmate (VII) by radial distribution analysis

A radial distribution analysis has been used to determine interatomic distances of the statistically oriented OsO₃N⁻ entity in potassium nitridoosmate(VIII). An isolated peak in the experimental distribution function with a maximum at 1.75 Å is interpreted in terms of one OsN pair with d(Os–N) = 1.63 Å and three OsO pairs with d(Os–O) = 1.78 Å (error limit ±0.03 Å) by the corresponding pair-function distribution curve.
