(2RS,4SR)-7-Bromo-2-(2-methylphenyl)-2,3,4,5-tetrahydro-1H-naphtho[1,2-b]azepin-4-ol, C21H20BrNO, (I), and (2RS,4SR)-2-(3-methylthiophen-2-yl)-2,3,4,5-tetrahydro-1H-naphtho[1,2-b]azepin-4-ol, C19H19NOS, (II), both crystallize with Z = 2 in the space groups P21/c and Cc, respectively; compound (II) crystallizes as a nonmerohedral twin, with twin fractions 0.183(2) and 0.817(2). The molecules of (I) are linked by OH...O and OH...N hydrogen bonds to form a cyclic centrosymmetric R44(16) tetramer. The molecules of (II) are linked by OH...O hydrogen bonds to form a C22(4) chain and these chains are weakly linked by a single CH...(thienyl) interaction to form a three-dimensional array. Comparisons are made with some related compounds.
