Reactivity of [PtCl(η2-C2H4)(N-N)]+, N-N = diimine ligand, with phenol derivatives and first comparison between single crystal X-ray structures of syn- and anti-[Pt(N-N)(phenolate)2] rotamers in the solid state

• A new synthetic route for [Pt(N-N)(OC6H4-4-Me)2] complexes have been proposed.
• X-ray structure of 1b is the first reported syn- rotamer of a Pt(II) bis-phenolate complex.
• Syn- and anti-[Pt(N-N)(OC6H4-4-Me)2] rotamers have been compared for the first time.

In this work it is described a new synthetic pathway for the synthesis of bis-cresolate Pt(II) complexes with (N-N) dinitrogen ligands. In particular, we were able, for the first time, to isolate, in the solid state, both anti-[Pt(N-N)(OC6H4-4-Me)2], N-N = 1,10-phenanthroline, (head to tail) and syn-[Pt(N-N)(OC6H4-4-Me)2], N-N = 2,2′-bipyridyl, (head to head) rotamers, which were characterized as different rotamers in the solid state by single crystal X-ray diffraction.

A new synthetic procedure for [Pt(N-N)(OC6H4-4-Me)2] complexes and the first comparison between single crystal X-ray structures of syn- and anti-[Pt(N-N)(OC6H4-4-Me)2] rotamers have been reported.Figure optionsDownload as PowerPoint slide
