Treatment of the digallium compound R2Ga-GaR2 (1) [R = CH(SiMe3)2] with the dicarboxylic acids 1,2- and 1,4-(HO2CCH2O)2C6H4 afforded, by the release of H2C(SiMe3)2, macrocyclic compounds 2a and 2c, in which two organic spacer ligands connect two metal-metal bonds. Two CO2 groups bridge each Ga-Ga bond, and different structures resulted with a parallel or perpendicular arrangement of the bridging ligands. The resorcinol derivative 1,3-(HO2CCH2O)2C6H4 yielded the unique compound 2b, in which four Ga-Ga bonds are bridged by four spacer ligands. The organic groups form loops, which are alternately arranged above and below the mol. plane with four saddle points and a structure approaching 4 symmetry. The 1,2- and 1,4-diacids afforded tetrakis(digallium) compounds 3a and 3c in the presence of water. In both cases carboxylate groups and hydroxido ligands bridge two Ga atoms of two different Ga-Ga bonds. The spacer ligands connect two of these fragments and adopt parallel orientations to form mol. boxes. Again, the 1,3-diacid afforded a unique structural motif in which a Ga4O6 skeleton (two Ga-Ga bonds) is bridged by a single organic spacer, reminiscent of the handle of a basket.
