(E)-1-{4-[Bis(4-meth-oxy-phen-yl)meth-yl]piperazin-1-yl}-3-(3,4-dieth-oxy-phen-yl)prop-2-en-1-one ethanol disolvate.

ABSTRACT: The asymmetric unit of the title compound, C(32)H(38)N(2)O(5)·2C(2)H(6)O, contains one main mol-ecule and two solvent mol-ecules, which inter-act via inter-molecular O-H⋯O hydrogen bonds. The piperazine ring adopts a chair conformation. The crystal packing exhibits weak inter-molecular C-H⋯O hydrogen bonds and voids of 31 Å(3).
