Abstract

THE TITLE COMPOUND (SYSTEMATIC NAME: 4-{3-[2-aza-tricyclo-[9.4.0.0(3,8)]penta-deca-1(15),3,5,7,11,13-hexaen-2-yl]prop-yl}-1-(2-hy-droxy-eth-yl)piperazine-1,4-diium dichloride), C(23)H(31)N(3)O(+)·2Cl(-), is the dihydro-chloride of a piperazine derivative bearing a bulky 3-(5H-dibenz[b,f]azepin-5-yl)propyl substituent. Protonation took place on both N atoms of the piperazine unit. The diaza-cyclo-hexane ring adopts a chair conformation. N-H⋯Cl, O-H⋯Cl and C-H⋯Cl hydrogen bonding as well as C-H⋯O contacts connect the components into a three-dimensional network in the crystal. Two C-H⋯π contacts are also observed.
