Di- and tri-organogermanium carboxylates, [R2Ge(02CAr)2] and
[R3Ge(02CAr)] (R = Me, Et or Bu; Ar = C5H4N,
C9H6N), have been synthesized by the reactions of the corresponding dialkyldichloro germane and trialkylchloro/bromo germane with an appropriate sodium salt
of N-heterocyclic carboxylic acid, (C5H4N.COOH,
C9H6N.COOH), in 1:2 and 1:1 molar ratio in anhydrous benzene. These compounds have been characterized by elemental analysis, IR and NMR
(1H and I3C{1H}) spectroscopy. Molecular structures of
[Me3Ge(02CC9H6N)] and
[Et2Ge(02CC5H4N)2] have been determined unambiguously by X-ray diffraction study. The former has a distorted tetrahedral configuration around germanium with monodentate carboxylate group, while the latter has distorted trigonal bipyramidal geometry.
