SYNTHESIS AND CHARACTERIZATION OF IRIDIUM CHLORIDE COMPLEXES .1. USE OF N-ALKYLPHENOTHIAZINE DRUGS AS LIGANDS

Iridium complexes of N-alkylphenothiazines have been prepared in MeOH. The polynuclear complexes obtained have been characterized by element al analyses, magnetic susceptibilities, molar conductivities, thermogr avimetric analysis and spectral data. The molecular formulae of the ne w complexes are as follows: [Ir3(LH)4Cl10]Cl2.xMeOH, where L = chlorpr omazine (CP), promethazine (PM) or ethopropazine (EP), and x = 1 for C P and 2 for PM or EP; [Ir(TFH2)2Cl4] [IrCl6].MeOH, where TF = trifluop erazine; and [Ir3(TRH)2Cl11(MeOH)]Cl.MeOH and [Ir4(TRH)3Cl15], where T R = thioridazine. The complexes are diamagnetic in nature. Tentative s tructures are proposed for the complexes.
