Diethyl 2-[(morpholin-4-yl)(phenyl)methyl]malonate
Acta Crystallographica Section E Structure Reports Online, 2007 In the title compound, C18H25NO5, the morpholine unit adopts an almost ideal chair conformation. The crystal structure is consolidated by C—H⋯O intermolecular hydrogen-bond interactions, providing stabilization. The molecular conformation shows two possible pockets ready to coordinate two metal atoms.
