title: (M)- and (P)-8-[(1S,2R)-2-hydroxy-1-methyl-2-phenylethyl]-8-methyl-8, 9-dihydro-7H-dinaphth[2,1-c:1',2'-e]azepinium bromide solvates.
abstract: The title compounds are diastereoisomers with antipodean axial chirality. The M isomer crystallizes as a (1/3) acetone solvate, C(32)H(30)NO(+).Br(-).3C(3)H(6)O, while the P isomer crystallizes as a (1/1) dichloromethane solvate, C(32)H(30)NO(+).Br(-).CH(2)Cl(2). In each structure, O-H.Br hydrogen bonds link the cations and anions to give ion pairs. The seven-membered azepinium ring adopts the usual twisted-boat conformation and its ring strain causes a slight curvature of the plane of each naphthyl ring.
