About compounds containing 16-valence electron anions [XYZ] n− – a brief and current overview including some properties of such anions

Abstract

A short overview covering compounds containing 16-valence electron anions [XYZ] n− (fulminate: [CNO]−, cyanate: [OCN]−, azide: [NNN]−, carbodiimide: [NCN]2−, dinitridoborate: [NBN]3−, carbidonitridocarbonate: [CCN]3−, dicarbidocarbonate: [CCC]4−, carbidonitridoborate: [CBN]4−, dicarbidoborate [CBC]5−) is given, including some of their structural properties, e.g., the ranges of the bond lengths, the bond angles and volume increments of the respective anion (either taken from literature or calculated from selected experimental data). The force constants, the experimentally determined bond lengths and angles are given for one representative compound per anion. The numbers presented here are briefly compared and discussed.
