4,5,7-Trimeth-oxy-2-methyl-3-(2,4,5-trimethoxy-phen-yl)-1-[3-(2,4,5-tri-methoxy-phen-yl)pentan-2-yl]indane acetone 0.858-solvate.

In the title compound, C(36)H(48)O(9).0.858C(3)H(6)O, the five-membered ring adopts an envelope conformation. The acetone solvent mol-ecule was disordered and was refined over two positions with equal occupancies, giving an overall occupancy of 0.858 (4). There are weak intra-molecular C-H⋯O hydrogen bonds and intermolecular C-H⋯π inter-actions in the structure.
