摘要：
The reaction of GaCl3 with 1,8-bis(trimethylstannyl)biphenylene produces the tetragallium macrocycle (C12H6)(4)Ga4Cl4 (1) in high yield. Compound 1 contains a cyclic array of four Ga(biphenylene) units that form a 20-membered ring. The Ga atoms are bridged by mu(2)-Cl atoms so that the Ga atoms are four-coordinate. The structure adopts a saddle-shaped conformation with approximate D-2d symmetry. 1 reacts with Lewis bases (CH3CN and THF) and halide ions (Cl- and Br-) to form (C12H6)(2)Ga2Cl2L and (C12H6)(2)Ga,Cl2X- species.
