The reaction of gallium trimethyl with the dibenzo-tetra-aza macrocycle, C22H24N4, results in the formation of the dimethyl gallium-macrocycle, [Me2Ga(C22H23N4)]. A single crystal X-ray diffraction study of the complex shows the gallium to be in a near tetrahedral environment and bonded to two of the four nitrogen atoms, with two nearly equal Ga-N distances. The other two nitrogen atoms form an internal hydrogen bond (N...N 2.675(8) angstrom). The compound loses an additional mole of methane above 200-degrees-C and is converted quantitatively into the monomethyl derivative [MeGa(C22H22N4)].
