摘要

The crystal structures of bis#173;{3,5-di#173;fluoro-2-4-(2,4,6-tri#173;methyl#173;phen#173;yl)pyridin-2-ylphenyl-#954;2N,C1}(picolinato-#954;2N,O)iridium(III), Ir(C20H16F2N)2(C6H4NO2), 1, and bis#173;2-(4-tert-butyl#173;pyridin-2-yl)-3,5-di#173;fluoro#173;phenyl-#954;2N,C1(picolinato-#954;2N,O)iridium(III), Ir(C15H14F2N)2(C6H4NO2), 2, are presented herein. These phospho#173;rescent cyclo#173;metallated iridium(III) compounds have been structurally investigated in order to better understand the nature of their blue-shifted emssions while maintaining high quantum yields. Compound 1 exhibits substantial twisting of the mesitylene rings out of the plane of the attached pyridine ring, with dihedral angles of 67.0#8197;(1) and 78.7#8197;(1)#176; between the best mean planes. For both compounds, the contribution of disordered solvent mol#173;ecule(s) was removed using the SQUEEZE Spek (2015). Acta Cryst. C71, 9#8211;18 routine in PLATON Spek (2015). Acta Cryst. C71, 9#8211;18. These solvent mol#173;ecules are not considered in the given chemical formula and other crystal data.
