The chloropnictines (η-C5Me5)2AsCl (1), (η-C5Me5)2SbCl (2), and (η-C5Me5)2BiCl (3) have been prepared by treatment of the appropriate element trichloride with LiC5Me5. X-ray crystallographic assays establish that in the case of 1, both C5Me5 rings are attached to As in an η1(σ) fashion. In 2 and 3, the C5Me5 rings are π delocalized and feature tri- and pentahapto ring binding, respectively, to the group 15 element. Conversion of 1 and 2 to the salts [As(η-C5Me5)2][AlCl4] (4) and [Sb(η-C5Me5)2][AlCl4] (5) was effected by reaction with the stoichiometric quantity of Al2Cl6. The X-ray crystal structure of 4 is surprisingly complex and features four independent ion pairs in the asymmetric unit with a variety of hapticities for the π-bonded C5Me5 rings. The structure of the stibocenium cation of 5 involves bis(η4) attachment of the π-bonded C5Me5 rings.Key words: main group metallocenes, arsocenium cations, stibocenium cations, group 15 pentamethylcyclopentadienyl chlorides.
