    Notes: The new tetraazido complexes of aluminium, gallium, and indium [thf2Na][thf2Al(N3)4] (1), [py2Na][py2In(N3)4] (2), and Na[Ga(N3)4] (3) have been synthesized from MCl3 and NaN3 by salt metatheses and characterized by X-ray diffraction analysis. In compounds 1 and 2, the Group 13 metal atom and the sodium atom are each hexacoordinated by four azido groups and two additional solvent molecules. The azido groups act as μ(1,3)-bridging ligands between the Group 13 metal and sodium, thereby forming network structures. In contrast, complex 3 is solvent-free and exhibits a tetracoordinated gallium centre and a heptacoordinated sodium atom. The structure of 3 has also been investigated by means of X-ray powder data and the Rietveld method and the results are compared with the single-crystal data.
