Abstract

The ³¹P NMR spectra of complexes of the type Pt(SeSN₂)(PR₃)₂ and Pt(Se₂N₂(PR₃)₂) display trans ²J{⁷⁷Se³¹P} couplings of ca. 30–80 Hz, with no corresponding cis coupling; in contrast Pt(TeSN₂)(PMe₂Ph₂ has both trans and cis ^J{¹²⁵Te³¹} coupling of 146 Hz and 103 Hz respectively. The ³¹ spectra of the complexes Pt(S₂¹⁵N₂)(PMe₂)P₂ nd [Pt(S₂¹⁵N₂)Cl(PMe₂)Ph)]⁻ show both ²J‐ and ⁴J{15N³¹P} couplings, which alter substantially upon protonation of the S₂N₂²⁻ ligand. The ¹⁵N NMR spectra of Pt(S₂¹⁵N₂H)Cl(PMe₂Ph) and Pt(S₃¹⁵N)Cl(PMe₂Ph) show the presence of both ³¹P¹⁵N and ¹⁹⁵Pt¹⁵N couplings but no significant ¹⁵N¹⁵N interactions.
