摘　　要：以5-(4-氟苯基)-1,3-二甲基-1H-1,2,4-三唑(fdpt)为环金属配体、乙酰丙酮(Hacac)为辅助配体合成出一种新型铱(Ⅲ)配合物Ir(fdpt)2(acac)。采用元素分析、红外光谱、核磁共振谱分析和单晶X衍射对其组成和化学结构进行了表征。结果表明,该配合物化学组成为C_(25)H_(25)F_(2)Ir N_(6)O_(2),属于单斜晶系,P2_(1/c)空间群。晶胞参数为a=1.58917(14)nm,b=1.64798(15)nm,c=1.06146(9)nm,β=94.741(3)°,V=2.7704(4)nm^(3),Z=4。A new iridium(Ⅲ)complex Ir(fdpt)2(acac)was synthesized with 5-(4-fluorophenyl)-1,3-dimethyl-1H-1,2,4-triazole(fdpt)as the ring metal ligand and acetylacetone(Hacac)as the auxiliary ligand.Its composition and chemical structure were characterized by elemental analysis,IR,NMR and single crystal X-ray diffraction.The result show that that chemical composition of the complex is C_(25)H_(25)F_(2)Ir N_(6)O_(2),which belongs to monoclinic system and P2_(1/c)space group.The unit cell parameter is a=1.58917(14)nm,b=1.64798(15)nm,c=1.06146(9)nm,β=94.741(3)°,V=2.7704(4)nm^(3),Z=4.
