N2 - A neutral Iridium (III) complex [Ir(ppy)2(PPh3)(NCO)] has been synthesized and characterized by IR, 1H NMR, ESI mass spectra and elemental analysis. The crystal structure of the complex has been determined by X-ray analysis. The compound crystallizes in monoclinic, space group P21-/c with a=0.99447(4) nm, b = 1.480 82(6) nm, c=2.247 13(11) nm, β=101.183(2)°, V=3.246 4(2) nm3, Z=4, D c=1.647 g•cm-3, F(000)=1 592, R1=0.032 8 and wR2=0.098 7 (I>2σ(I)). The photoluminescence (PL) spectra of the complex in dichloromethane, chloroform and dimethylfomamide (DMF) show emission maxima at 485, 484 and 515 nm, respectively, corresponding to bluegreen light-emitting in dichloromethane and chloroform, green light-emitting in DMF. The results show that the PL maxima have red shifted in strong polar solvent. CCDC: 738942.
