Controlling the Architecture of Discrete Organotin Sulfide Molecules by Optimization of the Intramolecular Spacer Length

Measured approach : Organotin sulfide complexes adopt different structures depending on the length of the intramolecular organic spacer R, as shown by the synthesis of [(R x Sn 2 ) 2 (μ‐S) 6 ] (e.g.; 1 ) or [R x 4 Sn 12 S 20 ] ( 2 ). For [(R x Sn 2 ) 2 (μ‐S) 6 ], three different arrangements of the organic “straps” attached to [Sn 4 S 6 ] cages are realized for different length ranges of R x , whereas the longest spacer provokes a complete rearrangement of the inorganic core to form 2 . DFT investigations rationalized the experimental findings.
