The syntheses and characterization of a number of square-planar Rh(I) monocarbonyl complexes incorporating un-symmetrical, tridentate, pyrazolylgallate ligands in a meridional coordination mode are described. Oxidative addition reactions of these complexes are detailed and a facile migratory insertion reaction, following the addition of methyl iodide, has resulted in a five-coordinate square-pyramidal Rh(III) acetyl complex. Crystal structures of two compounds are presented, [Me2Gapz(OCH2CH2NH2)]Rh(CO) and [Me2Gapz(OCH2CH2NMe2)]Rh(COMe)I, and confirm the molecular arrangements predicted on the basis of other physical measurements. Crystals of the former are monoclinic, a = 10.212(2), b = 7.8484(5), c = 16.733(2) Å, β = 105.133(6)°, z = 4, space group P21/c; and those of the latter are monoclinic, a = 10.0960(11), b = 11.5352(8), c = 15.871(2) Å, β = 105.764(6)°, z = 4, space group P21/n. Both structures were solved by conventional heavy atom methods and were refined by full-matrix least-square procedures to R = 0.026 and 0.036, respectively, for 2142 and 2941 reflections with I ≥ 3σ(I).
