Stabilisierung von M⁺-Ionen (M = In, Tl) durch Dibenzyldichlorogallat

Stabilization of M⁺ Ions (M = In, Tl) by Dibenzyldichlorogallate

MCl reacts with (PhCH₂)₂GaCl to give M[(PhCH₂)₂GaCl₂] [M = In (1), Tl (2)]. 1 and 2 were characterized by NMR, IR and MS techniques. In addition, an X-ray structure determination of 1 was performed. According to this, 1 consists of four-membered In₂Cl₂ rings connected by weak In…Cl contacts (344 pm) along [010] to a coordination polymer. The In⁺ ion is coordinated by four In–Cl and two In-aryl interactions.
