我已经构建了以下共振结构,但我想用点而不是破折号来表示键合电子。对于双键,我可以使用\:
并得到类似X::Y
,但对于三键,我该怎么做才能得到类似X⋮⋮Y
? :(
我希望你可以帮助我。
\documentclass{article}
\usepackage{chemfig}
\begin{document}
\setchemfig{atom style={scale=.85},arrow coeff=.85,atom sep=2.5em}
\schemestart%
\chemname{%
\chemleft[ \chemfig{%
\charge{180=\:}{S}~C-\charge{0=\:,90=\:,270=\:}{N}%
} \chemright]\chemmove{\node[] at (2pt,6pt) {\footnotesize $-$};}}%
{Estructura 1}%
\arrow(.mid east--.mid west){<=>}%
\chemname{%
\chemleft[ \chemfig{%
\charge{90=\:,270=\:}{S}=C=\charge{90=\:,270=\:}{N}%
} \chemright]\chemmove{\node[] at (2pt,6pt) {\footnotesize $-$};}}%
{Estructura 2}%
\arrow(.mid east--.mid west){<=>}%
\chemname{%
\chemleft[ \chemfig{%
\charge{90=\:,180=\:,270=\:}{S}-C~\charge{0=\:}{N}%
} \chemright]\chemmove{\node[] at (2pt,6pt) {\footnotesize $-$};}}%
{Estructura 3}%

答案1
你想要这样的东西吗?
\begin{document}
\setchemfig{atom style={scale=.85},arrow coeff=.85,atom sep=2.5em}
\schemestart%
\chemleft[
\chemfig{\charge{180=\:}{S}\vdots \vdots C-\charge{0=\:,90=\:,270=\:}{N}} \chemright]
\schemestop
\end{document}
...或者这样?
\begin{document}
\setchemfig{atom style={scale=.85},arrow coeff=.85,atom sep=2.5em}
\schemestart%
\chemleft[
\chemfig{\charge{180=\:,35=\.,0=\.,325=\.}{S}\,\,\, \charge{180=\.,150=\.,210=\.,0=\.}{C}\,\,\,\charge{180=\.,0=\:,90=\:,270=\:}{N}} \chemright]
\schemestop
\end{document}
