文摘

A macrocyclic gallium carboxylate (3) is formed on reaction of the digallane(4) R₂Ga-GaR₂ [R = CH(SiMe₃)₂], 1, with naphthalene-2,6-dicarboxylic acid, HOOC-C₁₀H₆-COOH.The macrocycle comprises 44 atoms, and four Ga-Ga single bonds are connected by fourdicarboxylato bridges. The cavity of the heterocycle may be described as a rigid molecularsquare possessing a largest diameter of 1.86 nm. It encloses four 1,2-difluorobenzenemolecules.
