^ If the last character of the template input is }, MediaWiki will confuse it with the end-of-template tag }}. Adding | between the two resolves this ambiguity. Other options include instead inserting (space), {{null}} or <nowiki/>.

Formulas (without charge) are just written. Eg.:

  • {{chem2|CH3(CH2)5CH3}} gives CH
    3
    (CH
    2
    )
    5
    CH
    3
  • {{chem2|Fe3S2(CO)9}} gives Fe
    3
    S
    2
    (CO)
    9
  • {{chem2|C_{''n''}H_{2''n''+2}|}} gives C
    n
    H
    2n+2

Charges are written inside parenthesis, otherwise its treated as +1 or −1, e.g.:

  • {{chem2|Na+}} gives Na+
  • {{chem2|O2-}} gives O
    2
    but can be written as {{chem2|O2(-)}} too.
  • {{chem2|SO4(2-)}} gives SO2−
    4
  • {{chem2|S19(2+)}} gives S2+
    19

Chemical equations can be written too. E.g.:

  • {{chem2|2 S + 3 O2 + 2 H2O -> 2 H2SO4}} gives 2 S + 3 O
    2
    + 2 H
    2
    O → 2 H
    2
    SO
    4
  • {{chem2|2S + 3O2 + 2H2O -> 2H2SO4}} gives 2S + 3O
    2
    + 2H
    2
    O → 2H
    2
    SO
    4

The arrows can be written as -> or just . All characters (and unicode markup) are valid input except \, = (Mediawiki use it), _ and - (endash etc.)

  • {{chem2|2 H2_{(g)} + O2_{(g)} -> 2H2O_{(g)}|}} gives 2 H
    2

    (g)
    + O
    2

    (g)
    → 2H
    2
    O
    (g)
  • {{chem2|NH2RCHCO2H <-> NH3+RCHCO2-}} gives NH
    2
    RCHCO
    2
    H ⇌ NH+
    3
    RCHCO
    2

Hapticity and mu:

  • {{chem2|W(CO)3(PiPr3)2(\h{2}\-H2)}} gives W(CO)
    3
    (PiPr
    3
    )
    2
    2−-H
    2
    )
  • {{chem2|auto=yes|W(CO)3(PiPr3)2(\h{2}\-H2)}} gives W(CO)
    3
    (PiPr
    3
    )
    2
    (η2−-H
    2
    )

Links: Use link=<wiki page> or ordinary wiki link ([[ and ]]), e.g.:

  • {{chem2|link=Iron(III) chloride|FeCl3}} gives FeCl
    3
  • {{chem2|3[[hydrogen|H2]] + 2[[nitrogen|N2]] <-> 2[[ammonia|NH3]]}} gives 3H
    2
    + 2N
    2
    ⇌ 2NH
    3

Auto links: Automatic link elements: Use auto=<something> (e.g. yes):

  • {{chem2|auto=yes|CH3CH2CH3CBrFCIClCH3}} gives CH
    3
    CH
    2
    CH
    3
    CBrFCIClCH
