Abstract
The colourless solid NO(HSO4), known as "lead-chamber crystals", was investigated ever since its first preparation more than two centuries ago. Its overall ionic nature now is confirmed by X-ray crystallography [Pna2(1), a = 7.3558(4), b = 6.8924(3), c = 7.7017(3) angstrom, Z = 4]. The next neighbours of the NO+ cations are four hydrogensulfate oxygen atoms, forming a distorted square at a distance of about 2.5 angstrom from the nitrogen atom. The square pattern next to the nitrogen atom is the most widespread coordination figure about an NO+ ion in a nitrosyl salt. Depending on the anion, the interaction goes along with a decrease of the N-O stretch's excitation energy.
