Abstract

original image

Surrounded by selenium: Pulse field gradient spin-echo (PGSE) NMR diffusion studies of a mixture of oligomeric 1,2-diselenolene PtIV 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 {PtIVSe6} (1) and {PtIV2Se10} (2).
