Thermally induced Lengthening of weak Dative Bonds in Donor Functionalized Organoaluminum Alkoxides observed by X-ray Single Crystal Diffraction

The X-ray structure analysis of the alkylaluminum and -indium compounds derived from methyl thiosalicylate, Me 2 Al(SC 6 H 4 -2-CO 2 Me) and [Me 2 In(µ-SC 6 H 4 -2-CO 2 Me)] 2 , revealed that the intermolecular S···C(π) interaction between the Al-S thiolate units and the ester π-surface can effectively compete with the hypercoordinate sulfur-metal dative bond. The former compound exists as the noncovalently bonded

The structures of [(iPr 3 P) 2 Cu(μ-SSiMe 3 )(InMe 3 )] and [(iPr 3 P) 2 -Cu(μ-SeSiMe 3 )(InMe 3 )] were determined by single-crystal X-ray diffraction. Both complexes are Lewis acid-base adducts of the InMe 3 acceptor and the chalcogen donor atom linking a Me 3 Si group and a (iPr 3 P) 2 Cu moiety. They are very [a]4727 unstable under atmospheric conditions and decompose at ambient temperatures. Results of DFT calculations for these complexes and the related hypothetical [(Me 3 P) 2 Cu(μ-SSi-Me 3 )(InMe 3 )] compound show that the unusual planar coordination of the chalcogen atoms is due to steric crowding.
