The photodecomposition product μ-oxalato-1κ^2O,O′:2κ^2O″,O‴-bis{bis[2-(2-pyridyl)phenyl-κ^2C,N]iridium(III)}–acetone (1/1.974)
Abstract
An attempt to grow crystals of [Ir(ppy)_2(vacac)], (I), from an acetone-d_6 solution formed instead crystals of [{Ir(ppy)_2}_2(μ-oxalato)] acetone solvate, (II), [Ir_2(C_(11)H_8N)_4(C_2O_4)]·1.974C_3H_6O, where ppy is the phenylpyridine anion and vacac is vinylacetylacetonate. Each Ir^(III) ion in (II) is in a pseudo-octahedral coordination environment, where the pyridine N atoms are trans to each other and the phenyl C atoms are trans to the O atoms of the oxalate bridging ligand. There are two crystallographically independent dimer molecules, each lying on an inversion centre. It is suggested that the oxalate ligand is formed in a series of steps initiated by the aldol condensation of acetone with vacac.
