Crystallographic Distinction between “Contact” and “Separated” Ion Pairs:  Structural Effects on Electronic/ESR Spectra of Alkali-Metal Nitrobenzenides [PDF]

open access: yes, 2004
The classic nitrobenzene anion-radical (NB-• or nitrobenzenide) is isolated for the first time as pure crystalline alkali-metal salts. The deliberate use of the supporting ligands 18-crown-6 and [2.2.2]cryptand allows the selective formation of contact ...
