Our LaTeX macros support LaTeX as well as mhchem.
There are 2 LaTeX macros available:
LaTeX (Block) for block level equations
LaTeX (Inline) for inline equations

\ce{CO2 + C -> 2 CO}
Output:
Example 2.
Macro body:
\ce{Hg^2+ ->[I-] HgI2 ->[I-] [Hg^{II}I4]^2-}
Output:
Chemical formulae
Example 1.
Macro body:
\ce{H2O}
Output:
Example 2.
Macro body:
\ce{Sb2O3}
Output:
Charges
Example 1.
Macro body:
\ce{CrO4^2-}
Output:
Example 2.
Macro body:
[AgCl2]-
Output:
Nuclides, isotopes
Example 1.
Macro body:
\ce{^{227}_{90}Th+}
or
\ce{^227_90Th+}
Output:
Example 2.
Macro body:
\ce{^{0}_{-1}n^{-}}
or
\ce{^0_-1n-}
Output:
It might be ambiguous whether a superscript belongs to the left or right element. There is automatic detection (digits only = mass number = belongs to right side), but to make sure you can type {} as a separator.
Example 3.
Macro body:
\ce{H{}^3HO}
or
\ce{H^3HO}
Output:
Reaction arrows
Example 1.
Macro body:
\ce{A -> B}
Output:
Example 2.
Macro body:
\ce{A <- B}
Output:
Example 3.
Macro body:
\ce{A <-> B}
Output:
Not to be used according to IUPAC and ACS
Example 4.
Macro body:
\ce{A <--> B}
Output:
Example 5.
Macro body:
\ce{A <=> B}
Output:
Example 6.
Macro body:
\ce{A <=>> B}
Output:
Example 7.
Macro body:
\ce{A <<=> B}
Output:
Each arrow can take two optional arguments: one for above and one for below. The arrow arguments use the same input syntax as the \ce command.
Example 8.
Macro body:
\ce{A ->[H2O] B}
Output:
Example 9.
Macro body:
A ->[{text above}][{text below}] B}
Output:
Example 10.
Macro body:
\ce{A ->[$x$][$x_i$] B}
Output:
Parentheses, brackets, braces
Use parentheses ( ) and brackets [ ] normally. Write braces as \{ \}.
Example 1.
Macro body:
\ce{(NH4)2S}
Output:
Example 2.
Macro body:
\ce{[\{(X2)3\}2]^3+}
Output:
For large parentheses, \left and \right macros need to be in the same math environment, so you might have to put \ce into $ into \ce, but that’s fine.
Example 3.
Macro body:
\ce{CH4 + 2 $\left( \ce{O2 + 79/21 N2} \right)$}
Output:
