A niobium-necked cluster [AsNb(AsSn)] with aromatic Sn
We describe here the synthesis and characterization of a ternary cluster compound [As 3 Nb(As 3 Sn 3 )] 3− ( 1 ), in which a niobium( v ) atom is coordinated by an As 3 3− triangle and a bowl-type As 3 Sn 3 5− ligand. Cluster 1 was synthesized by dissolving K 8 NbSnAs 5 ( 2 ) in the presence of [2.2...
