Abstract

Six tributylstannyl citrates and three tributylstannyl propane-1,2,3-tricarboxylates of the formula R<sup>1</sup>C(CH<sub>2</sub>COOR<sup>2</sup>)(COOR<sup>3</sup>)(CH<sub>2</sub>COOR<sup>4</sup>) (R<sup>1</sup> = OH or H, R<sup>2</sup>, R<sup>3</sup>, R<sup>4</sup> = H, Bu<sub>3</sub>Sn, C<sub>6</sub>H<sub>11</sub>NH<sub>3</sub>, (C<sub>6</sub>H<sub>11</sub>)<sub>2</sub>NH<sub>2</sub> or (CH<sub>2</sub>)<sub>5</sub>NH<sub>2</sub>) have been synthesised, and their solution and solid-state structures studied by infrared, <sup>1</sup>H, <sup>13</sup>C and <sup>119</sup>Sn NMR, <sup>13</sup>C and <sup>119</sup>Sn CP/MAS NMR and <sup>119</sup>Sn Mössbauer spectroscopies. In non-coordinating solvents, the compounds exist as isolated molecules or ionic-pairs with their tin atoms in pseudotetrahedral environments. In coordinating solvents, the tin atoms in the compounds are five-coordinate owing to the participation of the solvent in bonding; and their <i>trans</i>-trigonal bipyramidal coordination spheres consist of the <i>ipso</i>-carbon atoms of the butyl substituents in equatorial plane, and the solvent molecule and the oxygen atom of the monodentate carboxyl group in axial positions. A part of tributylstannyl groups together with some bidentate bridging carboxylate groups form polymeric chains in the solid state of citrates and propane-1,2,3-tricarboxylates. Also dioxastanna-rings with the participation α-hydroxycarboxylate fragments and one of the tributylstannyl groups occur probably in some citrates in the solid state. The spectroscopic assignment for the citrate has been confirmed by crystal structure analysis. <p>
