绘制化学分子结构 - chemfig - [ ] 居中

Question

我希望 [ ] 位于中心但我没有成功。

\chemfig{HO-[@{left,0.25}]CH_{2}CH_{2}O-[@{right,0.25}]OH}
\polymerdelim[delimiters ={[]}, height = 10pt, depth = 10pt, indice = n]{left}{right}

Answer 1

可能是您忘记了第二个尺寸参数（参见0.8）@{left,0.5}（例如），并且您将方括号放在中心。

\documentclass{article}
\usepackage{chemfig}
\begin{document}
\chemfig{HO-[@{left,0.5},0.8]CH_{2}CH_{2}O-[@{right,0.5},0.8]OH}
\polymerdelim[height=10pt, depth=10pt, indice=\!n, delimiters={[]}]{left}{right}
\end{document}
