As shown by the results, in the crystal structures where the strong formation groups of hydrogen-bonds lack, weak interactions such as CH/π, π/π and weak hydrogen-bond (C—H…X, X——O, N, Cl, Br) play important roles in the molecular self-assembling into crystal structures and affect the crystal symmetry.
结果表明:在这些缺少强氢键生成基团的晶体结构中,弱相互作用π/π,CH/π及弱氢键(C—H…X,X——O,N,Cl,Br)对分子自组装成晶体的过程及对晶体的对称性产生重要影响。
