The complexes [Bu-2(DMPA)SnOSn(DMPA)BU2](2) (2) and [BU2Sn(DMPA)(2)] (3), where HDMPA is 2-[bis(2,6-dimethylphenyl)amino]benzoic acid, have been prepared and structurally characterized by means of, vibrational, ultra-violet, H-1 and C-13 NMR spectroscopies. The crystal structure of complexes 2 and 3 have been determined by X-ray crystallography. Three distannoxane rings are present to the dimeric tetraorganodistannoxane of planar ladder arrangement of 2. The structure is centro-symmetric and features a central rhombus Sn2O2 unit with two additional tin atoms linked at the O atoms. Five- and six-coordinated tin centers are present in the dimmer distannoxane. The crystal structure of 3 consists of discrete molecular units and the two modeprononated ligands are co-ordinated to the SnBu2 fragment. The ligands act as anisobidentate chelating agents, thus rendering the tin atom sixco-ordinated. Significant pi-->pi, C-H-pi stacking interactions and intramolecular hydrogen bonds stabilize the structures 2 and 3. The polar imino hydrogen atom participates in intramolecular hydrogen bonds. Complexes 2 and 3 are self-assembled via pi-->pi, C-H-pi and stacking interactions. (C) 2003 Elsevier B.V. All rights reserved. (EN)
