The crystal structures of two arylcyclohexylamine derivatives, methoxmetamine hydrochloride (MMXE·HCl) and methoxetamine hydrochloride (MXE·HCl), were determined using laboratory X-ray powder diffraction data. Both compounds are known for anesthetic and sedative effects and have been used illicitly as recreational drugs. Structure determination was performed with DASH software and Rietveld refinements with TOPAS Academic, yielding monoclinic unit cells. For MMXE·HCl, the parameters were a = 15.0429(5) Å, b = 14.0721(5) Å, c = 6.5716(2) Å, β = 90.9864(14)°, V = 1,390.91(8) ų, with Z = 4 and space group P2₁/n. For MXE·HCl, the parameters were a = 8.7772(5) Å, b = 9.9528(7) Å, c = 8.5841(6) Å, β = 100.276(3)°, V = 737.
