2-{4-[3-(5H-dibenz[b,f]azepin-5-yl)prop-yl]piperazin-1-yl}ethanol), C(23)H(29)N(3)O, the 5H-dibenz[b,f]azepine and piperazine rings adopt boat and chair conformations, respectively, and the overall shape of the fused ring part of the molecule is a butterfly. In the crystal, O-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into a layer parallel to the bc plane.
