Nitrosolate und verwandte Verbindungen, XII Nitrosolatokomplexe von Silber(I) / Nitrosolates and Related Compounds, XII Nitrosolato Complexes of Silver(I)

Abstract

X-ray analysis shows silver(I) aminomethylnitrosolate to have dimers as structural units, in which the W-shaped nitrosolate ions act as μ2-bridging ligands via the nitrogen atoms of the NO groups. The nearly planar dinuclear complexes form stacks, which are connected by additional AgO contacts leading to a kind of layer structure. These layers are held together by hydrogen bonds. Mononuclear complexes of composition [Ag(nitrosolate)L2] can be obtained from silver(I) ethylnitrosolate and bipyridyl in methanol and from silver(I) benzylnitrosolate and triphenylphosphane in diethylether/liquid ammonia. In these complexes the nitrosolate ions are supposed to act as chelating ligands, again with N,N′-coordination.
