Abstract: The central Ge atoms in the structures of 3-(2-fluorophenyl)-3-(triphenylgermyl)propionic acid, [Ge(C₆H₅)₃(C₉H₈FO₂)], 3-(2-tolyl)-3-(tri-4-tolylgermyl)propionic acid, [Ge(C₇H₇)₃(C₁₀H₁₁O₂)], and 3-(4-tolyl)-3-(tribenzylgermyl)propionic acid, [Ge(C₇H₇)₃(C₁₀H₁₁O₂)], are four-coordinate with slightly distorted tetrahedral geometry. The Ge-Csp³ distances [1.970 (3)-1.997 (3) Å] are significantly longer than the Ge-C_aromatic distances [1.940 (3)-1.959 (2) Å]. In all three structures, the molecules form dimeric pairs about inversion centres through strong hydrogen-bonding interactions between carboxylic acid groups.

Formula: [Ge(C₆H₅)₃(C₉H₈FO₂)] and two isomers of [Ge(C₇H₇)₃(C₁₀H₁₁O₂)]
