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.
