The molecular geometry of the complex of gallium trichloride with ammonia, Cl3Ga.NH3, has been studied by electron diffraction. The most important internuclear distances in terms of ra parameters are as follows: r(Ga-Cl) = 2.142±0.005 Å, r(Ga-N) = 2.057±0.011 Å, r(Cl⋯Cl) = 3.642±0.010 Å and r(Cl⋯N) = 3.242±0.012 Å. As in the case of the aluminium analogue, the flat pyramidal configuration of the GaCl3 part of the complex suggests a planar equilibrium structure for free GaCl3. The distance between the donor and acceptor parts may indicate a somewhat weaker interaction than is the case in the aluminium analogue.
