The title compound, [Sb(C11H14NO) 3], is monomeric with the Sb atom located on a threefold axis. The complex exhibits distorted trigonal-antiprismatic geometry around the Sb atom, owing to the presence of intramolecular N -> Sb interactions. H center dot center dot center dot phenyl intermolecular interactions lead to the formation of dimers stacked along the c axis. The morpholine rings exhibit almost ideal chair conformations. No intermolecular interactions between the morpholine rings of neighbouring molecules were observed.
