The reaction of the complex [{Ir(μ‐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 [Ir 2 (μ 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 φ PL = 60 %, stemming from the lowest triplet state of the 3 MLCT/LC character.
