What's the error reporting from CASTEP output file?
Obviously, you have to add the omitted hydrogen atoms as well as the methyl ligands manually. Maybe this is the problem.
good luck

謝謝您,另外想請教一下  1. 在添加3D分子結構的官能基時,空間角度那些重要嗎?  2. 能否用2D分子模型?砟M?

輸出文件只有下面幾個

其中.castep顯示
Pseudo atomic calculation performed for H 1s1
Converged in 13 iterations to a total energy of -12.4601 eV
  Pseudo atomic calculation performed for C 2s2 2p2
Converged in 17 iterations to a total energy of -145.7942 eV
Pseudo atomic calculation performed for N 2s2 2p3
Converged in 21 iterations to a total energy of -262.6886 eV
Pseudo atomic calculation performed for O 2s2 2p4
Converged in 23 iterations to a total energy of -429.2136 eV

到這裡就Fail了,想破頭啦>_<

虽然软件能够自动优化结构,但是初始结构不能与真实的偏差太多。
这个分子边缘有甲基,所以不是2D结构。
good luck
