Dicarbonyl[2-hydroxy-3,5,7-tris- (morpholinomethyl)cyclohepta-2,4,6- trienonato(1–)-j2O1,O2]rhodium(I)

In the title compound, [Rh(C22H32N3O5)(CO)2], the RhI 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 intramolecular C—H N and intermolecular C—H O hydrogen bonds, and – stacking interactions between the tropolone rings [centroid–centroid distance = 3.590 (8) A ° ] are observed in the crystal structure.National Research Foundation (South Africa
