| Abstract: | C20H16 (1) Mr = 256.34 and C20H14 (2), Mr = 254.32 are isomorphous, orthorhombic, P212121, Z = 4. For (?), ?a= 7.116(1), b =7.874(2), c = 24.564(4) A, V = 1376.4(3) A3, Dx = 1.237 g cm-3, μ(Mo-K α) =0.65 cm-1 , final R = 0.047 for 1152 observed reflections; for 2, a=6.963(2), b = 7.985(4), c = 24.315(8) A, V = 1351.9(8) A3, Dx = 1.250 g cm-3,μ(Mo-Kα) = 0.66 cm-1 , final R = 0.076 for 886 observed data. Structuralfeatures are similar to those of the parent [2.2]paracyclophane and related derivatives. |
