Synthesis and Characterization of Iridium CHLORIDE Complexes. II. Use of Phenothiazines Without N-Alkyl Side Chain as Ligands

Abstract

Iridium complexes of some phenothiazine derivatives have been prepared in MeOH or EtOH medium. The complexes have been characterized by elemental analyses, molecular weight, magnetic susceptibility, molar conductivity, and spectral data. The molecular formulas of the new complexes are [lr₂(pz)₅Cl₄(MeOH)]CI (where pz = phenothiazine), [Ir₂(cpz)₄]Cl ˙MeOH (where cpz = 2-chlorophenothiazine), [lr₂(apz)₅Cl₅]Cl ˙3MeOH (where apz = 2-acetylphenothiazine), [lr₃(dopz)₂Cl₅(EtOH)][lr₂Cl₄(EtOH)₂] ˙4EtOH (where dopz = 3,7-dinitro-5-oxophenothiazine) and [lr(tmpz)₅Cl]Cl ˙EtOH (where tmpz = trifluoromethyl-phenothiazine).
