A neutral Iridium(Ⅲ)complex[Ir(ppy)_2(PPh_3)(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 P2_1/c with α=0.99447(4)nm,b=1.48082(6)nm,c=2.247 13(11)nm,β=101.183(2)°,V=3.2464(2)nm~3,Z=4,D_c=1.647 g·cm~(-3),F(000)=1 592,R_1=0.032 8 and wR_2=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.
