Abstract

The structures of a series of spherical host-guest complexes [{MeE(PPh)(3)Li-4 center dot 3thf}(4)(mu(4)-X)](-) (E = Al, [1X](-); E = Ga, [2X](-); E = In, [3X](-)) reveal that changing the halide ions (X = Cl, Br, or I) within their central tetrahedral Li-4 sites has negligible effect on the structural parameters.
