Crystal structures of the (η²:η²-cyclo-octa-1,5-diene)(η⁶-toluene)-iridium(I) cation and μ-chlorido-iridium(III) complexes of 2-(phosphinito)- and 2-(phosphinometh-yl)anthra-quinone ligands.

ABSTRACT: When reacted in dry, degassed toluene, [Ir(COD)Cl]₂ (COD = cyclo-octa-1,5-diene) and 2 equivalents of 2-(di-tert-butyl-phosphinito)anthra-quinone (^tBuPOAQH) were found to form a unique tri-iridium compound consisting of one monoanionic dinuclear tri-μ-chlorido complex bearing one bidentate ^tBuPOAQ ligand per iridium, which was charge-balanced by an outer sphere [Ir(toluene)(COD)]⁺ ion, the structure of which has not previously been reported. This product, which is a toluene solvate, namely, (η²:η²-cyclo-octa-1,5-diene)(η⁶-toluene)-iridium(I) tri-μ-chlorido-bis-({3-[(di-tert-butyl-phosphan-yl)-oxy]-9,10-dioxoanthracen-2-yl}hydridoiridium(III)) toluene monosolvate, [Ir(C₇H₈)(C
