The complex (III) is converted into its corresponding tetraphenylborate salt (96% yield) which is investigated crystallographically (space group P21, Z=2).

The diamagnetic title complex is prepared by 1:1 molar reaction of trans‐bis(8‐hydroxyquinolinato)‐Pt(II) with TCNQ in refluxing acetonitrile and characterized by VIS and IR spectra, magnetic susceptibility and EPR measurements, and an X‐ray structure analysis (space group P1, Z=1).

Addition of diazomethane (II) to the chelates (I) gives the complexes (III).

The title complex (I) reacts with NaOH under mild conditions to give the hydroxo‐bridged isomers (III) containing phosphine and phosphinite ligands.

Dissolving the paramagnetic Ir(IV) complex (I) in CH2Cl2or CHCl3yields in situ the title Ir(III) system, which on photolysis using light at 404 nm three new geometrical isomers gives with a quantum yield of 0.75.

The title complex (I) reacts with one equiv. of tetracyanoethylene and tetracyanoquinodimethane to give the compounds (II).

The automatization of a known analytical procedure is described.

UV‐Irradiation of the peroxo‐complexes (I) induces elimination of O2and generation of the corresponding oxometalloporphyrins (II).
