The o-iminobenzoquinone L1 was synthesized for the first time. It was found that the structure of the obtained complexes depends on the degree of shielding of the carbonyl oxygen atom in the starting o-iminobenzoquinone. The sterically hindered L1 forms a 1 : 1 adduct with InI3 (complex (L1)InI3 (I)). The absence of a substituent at position 2 of the o-iminobenzoquinone ring promotes the formation of bisligand ionic derivatives {[(L2)2InI2]InI4} (II) and {[(L3)2InI2]InI4} (III). The molecular structure of L1 and complexes I·0.5 toluene, II·toluene·0.5 hexane was established by X-ray diffraction analysis (CCDC nos. 2440874 (L1), 2440875 (I·0.5 toluene), 2440876 (II·toluene·0.5 hexane)).

Both compounds exhibit light absorption in the 250–550 nm range (ε = 58 000–1000 M–1 cm–1) in solution and in the solid state (Eg = 2.14–2.16 eV) and emit in the orange region (λmax = 558–585 nm), with the maxima of solid-state emission systematically red-shifted by approximately 25 nm compared to emission in solution.

According to X-ray diffraction data, the monoanionic alkoxide ligand in I is coordinated to the metal in the κ3-O,N,N-mode. Complex I catalyzes the addition of PhSiH3 to annulated N-containing heterocycles: quinoline, 4-methylquinoline, 6-methylquinoline, and isoquinoline. The reactions are chemo- and regioselective and proceed over periods of 24 to 120 h.
