A new complex Ir(ppy)_2(Hpda)(Hppy=2-phenylpyridine, H_2pda=pyridine-2,3-dicarboxylic acid) has been synthesized and characterized. According to single-crystal X-ray diffraction analyses, the title complex crystallizes in the monoclinic system, space group P21/n with a=8.5708(10), b=22.685(2), c=12.5722(15) ?, β=96.19(1)°, V=2430.2(5) ?~3, C_(29)H_(20)N_3O_4 Ir, Mr=666.22, Z=4, Dc=1.833 g/cm~3, F(000)=1304, μ=5.54 mm~(-1), λ(Mo Kα)=0.71073 ?, GOOF=1.02, the final R=0.049 and w R=0.119 for 4680 independent reflections with Rint=0.069. The title complex is of mononuclear structure. Intermolecular C–H···O hydrogen bonds and π-π stacking interactions result in the formation of a 3D supramolecular network. Photoluminescent spectra show that one intense emission band with the maximum of 516 nm can be observed in the title complex.
