Abstract As part of our investigation on histamine receptor antagonists, the structures of two 9-10-dihydroanthracene derivatives are reported: 4: C22H28N2; hexagonal, P61; a = 10.014(1), c = 34.556(7) Å; V = 3001.0(7)Å3; and Z = 6; 9:C19H19N: triclinic, P-1; a = 8.427(2), b = 12.806(3), c = 15.292(3) Å, α = 70.27(3), β = 80.83(3), γ = 72.98(3)°; V = 1482.0(6) Å3; and Z = 4. All non-aromatic rings in both molecules adopt a similar conformation. However, the three six-membered rings in the etheno-anthracene structure adopt a more regular boat form in spite of two sp2 carbon bridged atoms.
