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—Caromatic 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. |
