Zusammenfassung
The reaction of the complex [{Ir(-Cl)(ptpy)2}2] (1) with oxamide in methanol in the presence of sodium methylate as the base was investigated. During the reaction the new complex [Ir2(2-oxamidato-N,N,O,O)(ptpy)4] (2), ptpy = 2-(p-tolyl)pyridinato was obtained.

The reaction of the complex [{Ir(-Cl)(ptpy)2}2] (1) with oxamide in methanol in the presence of sodium methylate as the base was investigated. During the reaction the new complex [Ir2(2-oxamidato-N,N,O,O)(ptpy)4] (2), ptpy = 2-(p-tolyl)pyridinato was obtained. The molecular structure of compound 2 was determined by an X-ray diffraction study. 2 crystallized from dichloromethane/methanol as a dihydrate in the orthorhombic space group Pbcm. This new compound displays intense green phosphorescence, with phi PL = 60%, stemming from the lowest triplet state of the 3MLCT/LC character.
