Resum
The study of the reactivity of the 3-methoxyimino-2-phenyl-3H-indoles C6H4-4R1-1-[C8H4N-30-NOMe] [R1 = Cl (1a) or H (1b)] with cis-[PtCl2(dmso)2] has allowed the isolation of trans-[Pt{C6H4-4R1-1- [C8H4N-30-NOMe]}Cl2(dmso)] [R1 = Cl (2a) or H (2b)] and cis-[Pt{C6H4-4R1-1-[C8H4N-30-NOMe]}Cl2(dmso)] CH2Cl2 [R1 = Cl (3a) or H(3b)]. Their crystal structures confirm: (a) the existence of a PtANindole bond, (b) the relative arrangement of the Cl ligands (trans in 2a and 2b or cis in 3a and 3b) and (c) the anti- (E) configuration of the oxime. A comparative study of the spectroscopic and photo-optical properties of ligands and their platinum(II) complexes (2a, 2b, 3a and 3b) is also reported.
