Abstract— Donor-acceptor complexes of the Ga[N(C6F5)2]3 Lewis acid with pyridine and diethyl ether are prepared for the first time and characterized by single-crystal XRD. The gallium atom in the complexes has a trigonal-pyramidal environment with bond angles significantly differing from the tetrahedral ones, indicating a hindered character of the transformation of the Lewis acid from the free state to the geometry of the donor-acceptor complex.frame0
