Abstract The Raman and infrared spectra of the tetracoordinated SnS 4 compound spirocyclic bis(ethane‐1,2‐dithiolato[2‐]‐ S,S '‐tin(IV)) (1) and its related hexacoordinated SnS 4 L 2 complexes with pyridine (2), 2‐(2‐pyridyl)ethylamine (3) and 3‐aminopyrazole (4) were recorded and interpreted. The skeletal vibrations of SnS 4 and SnS 4 N 2 were asigned and are discussed. The tetrahedral SnS 4 core in 1, which has essentially T d symmetry changes into a square planar with D 4h symmetry when coordinating to the N‐donor ligands (2, 3 and 4). This change in structure and symmetry also causes the Sn‐S vibrations to change both in number and wavenumber.
