Abstract

In the title compound, C(32)H(30)N(2)O(7), the piperidone ring adopts a chair conformation and the five-membered ring of the dihydro-indenone ring system adopts an envelope conformation. Intra-molecular O-H⋯N and C-H⋯O hydrogen bonds occur. The dihedral angle between the two hydr-oxy-subsituted methoxy-phenyl rings is 71.12 (5)°. In the crystal structure, mol-ecules are connected by inter-molecular O-H⋯O hydrogen bonds, forming layers parallel to (001). These layers are further connected by C-H⋯O hydrogen bonds, forming a three-dimensional network.
