Unexpected ortho C–H bond activation in coordinated 7,8-benzoquinoline: synthesis and characterisation of heteroleptic Ir(iii)-7,8-benzoquinoline complexes

Two iridium(iii) complexes were isolated via the reaction of pyridine-2-aldoxime (Hpyrald) with 7,8-benzoquinoline (benzq)-derived iridium starting material, namely [(benzq)(2)Ir(μ-Cl)(2)Ir(benzq)(2)] (1). Among the two complexes, [Ir(III)(benzq)(2)(pyrald)] (2) and [Ir(III)(benzq-κN,κC(10))(benzq-κ...

The complex (2) presented a usual structure as expected.
