The reaction of 2,5‐dihydro‐4,5,5‐trimethyl‐2,2‐di‐2‐pyridyl‐imidazole‐1‐oxyl ( L ) with AgSbF 6 gives the complex [Ag 2 L 2 ] 2+ [SbF 6 – ] 2 which was characterized by X‐ray diffraction. – The complex (a biradical) forms a four‐membered ring with two Ag(I) ions and two imine nitrogen atoms of the imidazolines with a relatively short Ag – Ag distance [2.839(2) Å]. Magnetic measurements indicate that two nitroxide radicals are slightly coupled.
