Tin( IV ) isopropoxide solvate has been modified by treatment with methacrylic, benzoic and acetic acid. For carboxylate to tin ratios ranging from 1.4 to 2, a dimer, namely [Sn(μ 2 ‐O i Pr)(O i Pr)(O 2 CR) 2 ] 2 [R = (CH 3 )CCH 2 , C 6 H 5 , CH 3 ], is isolated. Its structure, as determined by X‐ray diffraction on the methacrylate derivative, is based on two seven‐coordinate tin atoms, terminal and bridging isopropoxy ligands, and purely chelating carboxylates. These compounds have also been characterized by 119 Sn, 1 H, and 13 C solution NMR and 119 Sn CP‐MAS NMR spectroscopy. The possible use of this dimer as a precursor for carboxylate‐modified tin–oxo clusters has been tested. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
