Abstract The diorganotin(IV) and triorganotin(IV) derivatives R 2 SnA (R = Me, n‐Pr, n‐Bu, n‐Oct) and (R 3 Sn) 2 A [R = Me, Ph, cyclohexyl (Cyh); A = an anion of diphenic acid] have been prepared and characterized by elemental analysis, IR, 1 H and 13 C NMR spectroscopies. Tetrahedral tin forms a part of a diphenate cyclic ring in the diorganotin complexes with unidentate carboxylates, which have further been used for the synthesis of cyclic acid anhydrides. The soluble dinuclear triorganotin complexes (Me, Ph) possess symmetrically bonded carboxylates while the less soluble compound (Cyh 3 Sn) 2 A has two asymmetrically bonded carboxylates. All have a trigonal bipyramidal structure with R 3 Sn units remote from each other.
