For the synthesis of 2, 3,5-dimethylpyridine (Aldrich, 98+%) was used as a solvent, and crystals were produced by heating a mixture with an approximate molar composition Ga:S:DPE:3,5-dimethylpyridine, 2:4.5:1:26, at 200 °C for 20 days.

Data collected using a Bruker X2 APEX 2 diffractometer (Mo Kαλ = 0.71073 Å), at 100 K. The structures were solved by direct methods using the program SIR92 and model refined using CRYSTALS. The C and N atoms of the amine molecules were modeled isotropically. In 2 some of the dipyridyl ligands were found to be disordered over two crystallographically inequivalent positions, and therefore their site occupancies refined. The data were treated with SQUEEZE to correct the effect of the disordered organic cations.
