The crystal and molecular structure of three homologue 1,4‐dialkanoyloxy‐biphenyls (SYM‐n)

The three homologue compounds with the general formula CnH2n+1COOC6H4C6H4OOCCnH2n+1 (SYM‐n) crystallize in the following space groups: SYM‐1: triclinic, P1, a = 7.400(6), b = 9.227(3), c = 10.579(3) Å, α = 85.97(3), β = 89.09(3), γ = 71.47(3)°; SYM‐2; monoclinic, P21/c, a = 11.712(7), b = 5.648(1), c = 12.408(6), Å, β = 103.84(3)°; SYM‐5: triclinic, P1, a = 5.505(4), b = 8.342(8), c = 24.79(2) Å, α = 86.67(3), β = 85.45(6), γ = 71.74(7)°. The structures have been solved by direct methods and refined to R = 0.075, 0.061 and 0.053, respectively. The packing arrangements show a layer‐like structure. The layers are almost separated for SYM‐1 as well as for SYM‐2 and interdigitated for the structure of SYM‐5.
