Heterocyclen als Liganden, VI: Die verbrückende Koordination eines 1,1′‐Diazaferrocens in einem zweikernigen Silberkomplex — eine ungewöhnliche Struktur

Heterocycles as Ligands, VI 1 . ‐ The Bridging Coordination of a 1,1′‐Diazaferrocene in a Dinuclear Silver Complex ‐ an Uncommon Structure [Ag 2 (μ‐pyr   2 * Fe) 2 ](BF 4 ) 2 · 2 MeOH ( 4 , pyr* = C 4 Me 4 N) is obtained by reaction of pyr   2 * Fe · 2 Hpyr* ( 3 ) with AgBF 4 in MeOH. The X‐ray structure of 4 shows the bridging coordination mode of the diazaferrocene ligands with a nearly linear geometry at the silver atoms.
