As part of our investigation on histamine receptor antagonists, the structures of two 9-10-dihydroanthracene derivatives are reported: 4. C22H28N2; hexagonal, P6(1); a = 10.014(1), c = 34.556(7) Angstrom; V = 3001.0(7)Angstrom(3); and Z = 6; 9: C19H19N: triclinic, P-1; a = 8.427(2), b = 12.806(3), c = 15.292(3) Angstrom, alpha = 70.27(3), beta = 80.83(3), gamma = 72.98(3)degrees; V = 1482.0(6) Angstrom(3); 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 sp(2) carbon bridged atoms.
