AbstractTetramethylstibonium and tetraphenylstibonium oxinate(1, 2) and anthranilate (4, 5) have been prepared from the antimony pentaorganyls and 8-oxy-quinoline or anthranilic acid, respectively. The crystal structure determination of 1 revealed covalent molecules with planar bidentate oxinate as part of a distorted coordination octahedron at antimony. -121Sb-Mößbauer spectra of 1, 2, 4, 5 and of tetramethylstibonium acetylacetonate (3) are also in agreement with covalent structures, but a pentacoordinate environment of Sb is more likely for the anthranilates 4, 5. The spectra of the hydrogendicarboxylates 6-9, however, point to ionic stuctures with, if any, only weak donor interactions of the anions with the stibonium cations.
