Dicarbonyl[2-hydroxy-3,5,7-tris(morpholinomethyl)cyclohepta-2,4,6-trienonato(1-)-²O¹,O²]rhodium(I)

T. N. Hill and G. Steyl

Abstract: In the title compound, [Rh(C₂₂H₃₂N₃O₅)(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 intramolecular C-HN and intermolecular C-HO hydrogen bonds, and - stacking interactions between the tropolone rings [centroid-centroid distance = 3.590 (8) Å] are observed in the crystal structure.
