A new type of intramolecular H ⋯ H ⋯ H interaction involving N–H ⋯ H(Ir)⋯ H–N atoms. Crystal and molecular structure of [IrH(η1-SC5H4NH)22-SC5H4N)(PCy3)]BF4·0.72CH2Cl2

Abstract
The iridium complexes, [Ir[graphic omitted])22-SC5H4N)(PCy3)](BF4), 1, and [Ir[graphic omitted])21-SC5H4NH)2(PCy3)](BF4)2, 2, [Cy = cyclohexyl] in the solid state and in CD2Cl2 solution contain a new type of intramolecular H ⋯ H ⋯ H interaction contained in ten-membered bicyclic rings S–C–N–H ⋯ H(Ir)⋯ H–N–C–S defined by the two-2-pyridiniumthiolate ligands coordinated in a monodentate fashion via sulfur to an iridium atom.
