Syntheses and molecular structures of the dimeric tin–platinum complex [LSnPtCl 2 (SMe 2 )] 2 ( 2 ), the tin–platinum clusters [{LSnPtCl(SMe 2 )} 2 SnCl 2 )] ( 3 ) and [(LSn) 3 (PtCl 2 )(PtClSnCl)(LSnOHCl)] ( 6 ) (L=MeN(CH 2 CMe 2 O − ) 2 ), and of the unprecedented tin(II) aminoalkoxide–tin oxide chloride complex [O(SnCl) 2 ⋅ (SnL) 2 ] ( 5 ) are reported. The compounds were characterized by NMR spectroscopy ( 1 H, 13 C, 119 Sn, 195 Pt), 119 Sn Mössbauer spectroscopy ( 1 – 3 , 6 ), electrospray ionization mass spectrometry, elemental analyses, and single‐crystal X‐ray diffraction analyses ( 2⋅ CH 2 Cl 2 , 3⋅ 2 C 4 H 8 O, 5 , 6⋅ 3CH 2 Cl 2 ). The tin(II) aminoalkoxide [MeN(CH 2 CMe 2 O) 2 Sn] 2 ( 1 ) behaves like a neutral ligand, inserts into a Pt−Cl bond, or is involved in rearrangement reactions with the different behavior occurring even within one compound ( 3 , 6 ). DFT calculations show that the tin–platinum compounds behave like electronic chameleons.
