The synthesis and structural characterization of a novel ionic Ga(III) five-coordinate complex [{CH3(C5H4N)}Ga(SCH2(CO)O)2]−[(4-MepyH)]+, (4-Mepy = CH3(C5H5N)) from the reaction between Ga2Cl4 with sodium mercapto-acetic acid in 4-methylpyridine is described. Under basic reaction conditions the mercapto ligand is found to behave as a 2e− bidentate ligand. Single crystal X-ray diffraction studies show the complex to have a distorted square-pyramidal geometry with the [(−SCH2(CO)CO−)] ligands trans. The compound crystallizes in the P21/c (No. 14) space group with a = 7.7413(6) Å, b = 16.744(2) Å, c = 14.459(2) Å, V = 1987.1(6) Å3, R(Fo) = 0.032 and RW = 0.038.
