In the title compound, [Rh(C(22)H(32)N(3)O(5))(CO)(2)], the Rh(I) atom is coordinated by two carbonyl ligands and two tropolonate O atoms in a distorted square-planar geometry. It is an example of a new type of tropolone derivative that has not been characterized via solid-state methods. Weak intra-molecular C-H⋯N and inter-molecular C-H⋯O hydrogen bonds, and π-π stacking inter-actions between the tropolone rings [centroid-centroid distance = 3.590 (8) Å] are observed in the crystal structure.
在标题化合物[Rh(C₂₂H₃₂N₃O₅)(CO)₂]中，Rh(I)原子由两个羰基配体和两个托酚酮O原子配位，呈扭曲的平面正方形几何构型。它是一种新型托酚酮衍生物的实例，尚未通过固态方法进行表征。在晶体结构中观察到了弱的分子内C-H⋯N和分子间C-H⋯O氢键，以及托酚酮环之间的π-π堆积相互作用[质心-质心距离 = 3.590(8) Å]。
