摘要：

Procedures are given for the preparations of fac-[Ir(tacn)(H2O)3](CF3SO3)3, fac-[Ir(tacn)(CF3SO3)3] and [Ir(tacn)2]Cl3.1/2HCl.4H2O (tacn = 1,4,7-triazacyclononane). The concentration acidity constants of fac-[Ir(tacn)(H2O)3]3+ were determined (25-degrees-C, 1.0 M NaClO4), [pK(a1)=5.912(10), pK(a2)=7.658(14) and pK(a3) = 9.319(17)]. The crystal structure of [Ir(tacn)2]Cl3.1/2HCl.4H2O was determined by single-crystal X-ray diffraction (Trigonal, R32, hexagonal axes, a = 8.043(2), c = 31.821(9) angstrom, Z = 3).
