Dinuclear organoplatinum(II) complexes containing N-methylbenzamide

Abstract

The preparation and characterization of cationic, dinuclear complexes of the type trans-[Pt(PPh3)2(σ-C6H4NHMe)-µ-L-Pt(PPh3)2(σ-C6H4NHMe)](OTf)2 (L = 4,4′-bipyridine, 4,7-phenanthroline, 4,4′-dipyrazolylmethane, and 1,1′-diphenyl-4,4′-dipyrazolylmethane; OTf = trifluoromethanesulfonate (triflate)) containing two C3-N-methylbenzamide ligands are described. The key structural feature of the cationic complexes is the presence of two convergent amide groups that may allow for charge-assisted, H-bonding interactions in solution with suitable heteroaromatic guest molecules such as nucleobases.Key words: organoplatinum(II) complex, organometallic host, dinuclear complex, N-methylbenzamide.
