Abstract

From the reaction of the molten salt Sn(AlCl₄)₂ with benzene the dimeric species [(η-C₆H₆)₂SnCl-(AlCl₄)]₂•C₆H₆(1) has been obtained. Compound 1, which was characterized by X-ray diffraction analysis, represents the first example for double arene complexation of a group 14 post-transition element. Each Sn center is η⁶-bonded to two molecules of benzene. The two benzene planes are inclined with respect to each other and form angles of 101.9° (Sn1) and 99.7° (Sn2), respectively. The two (η⁶-C₆H₆)₂Sn units of the dimer are linked by two direct chlorine bridges and two 1, 3-bidentate AlCl₄ groups. The crystal benzene molecule has no metal contacts. The coordination of the tin(II) centers is thus pseudooctahedral, and the entire dimer approaches non-crystallographic C_2h symmetry.
