Can someone help me to get a result like this with chemfig (or something else)?

enter image description here

i know to get this:

\documentclass{article}
\usepackage{chemfig}
\usepackage{mhchem}
\begin{document}
\chemname{\chemfig{Fe^{2+}(-[::90]G)(-[::-90]G)(-[::35]\ce{N-})(-  [::-35]N)(-[::-145]\ce{^{-}N})(-[::145]\ce{N})}}{Myoglobin}
\end{document}

how can i get the dashed bond and the second naming?

The overall structure is a simple table, so a tabular should do fine

\begin{tabular}{llll}
  \chemfig{...} & ... \\
  Myoglobin & ... \\
  Fleischfarbe \\
  purpurrot & ... 
\end{tabular}

As for the chemical formulas: using the bonds optional parameters they are quite easy with chemfig. Here is an example for one of the structures:

\documentclass{article}
\usepackage{chemfig}
\begin{document}

\chemfig{
  Fe|^{2+}
    (-[1,,1,,very thick]N^{-})
    (-[2,,1]G)
    (-[3,,1,,very thick,dotted]N)
    (-[5,,1,2,very thick]^{-}|N)
    (-[6,,1]NO)
    (-[7,,1,,very thick,dotted]N)
}

\end{document}

The parameters are

<bond>[<angle>,<length factor>,<departure atom>,<arrival atom>,<tikz options>]

  • @Jaska this is controlled by a parameter bond offset. Search the chemfig manual for \setbondoffset
