Reactivity of [Pt(?2-C2H4)Cl(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

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.
