In the solvated title compound, [Ir(CHN)(CHO)]·CHCOCH, the Ir ion adopts a distorted octa-hedral coordination environment resulting from its coordination by two ,-chelating 2,6-dimethyl-3-(pyridin-2-yl)pyridin-4-yl ligands and one ,-chelating 2,2,6,6-tetra-methylhepta-ne-3,5-dionate ligand. The ,-chelating ligands are perpendicular to each other [dihedral angle between the least-squares planes = 87.86 (5)°] and are arranged in a -, and -, fashion. In the crystal, pairwise C-H⋯π inter-actions between inversion-related Ir complexes are present, forming a dimeric structure. The title complex shows bright bluish-green emission with good quantum efficiency in solution at room temperature.
在溶剂化的标题化合物[Ir(CHN)(CHO)]·CHCOCH中,铱离子采用扭曲的八面体配位环境,这是由于它与两个η²-螯合的2,6-二甲基-3-(吡啶-2-基)吡啶-4-基配体和一个η²-螯合的2,2,6,6-四甲基庚烷-3,5-二酮配体配位所致。η²-螯合配体相互垂直[最小二乘平面之间的二面角 = 87.86 (5)°],并以η-和η-的方式排列。在晶体中,存在与反演相关的铱配合物之间的成对C-H⋯π相互作用,形成二聚体结构。标题配合物在室温下的溶液中显示出明亮的蓝绿色发射,具有良好的量子效率。
