Surrounded by selenium : Pulse field gradient spin‐echo (PGSE) NMR diffusion studies of a mixture of oligomeric 1,2‐diselenolene Pt IV complexes are performed to characterize the species in solution (see structure: n =0 ( 1 ), n =1 ( 2 ), n =2 ( 3 ); red Pt, green Se, blue N, gray C). The results are in accord with the single‐crystal X‐ray diffraction structures obtained for the chiral complexes {Pt IV Se 6 } ( 1 ) and {Pt IV 2 Se 10 } ( 2 ).
