^ 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 CH3(CH2)5CH3
  • {{chem2|Fe3S2(CO)9}} gives Fe3S2(CO)9
  • {{chem2|C_{''n''}H_{2''n''+2}|}} gives CnH2n+2

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

  • {{chem2|Na+}} gives Na+
  • {{chem2|O2-}} gives O2 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 O2 + 2 H2O → 2 H2SO4
  • {{chem2|2S + 3O2 + 2H2O -> 2H2SO4}} gives 2S + 3O2 + 2H2O → 2H2SO4

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 H2(g) + O2(g) → 2H2O(g)
  • {{chem2|NH2RCHCO2H <-> NH3+RCHCO2-}} gives NH2RCHCO2H ⇌ NH+3RCHCO2

Hapticity and mu:

  • {{chem2|W(CO)3(PiPr3)2(\h{2}H2)}} gives W(CO)3(PiPr3)22-H2)
  • {{chem2|auto=yes|W(CO)3(PiPr3)2(\h{2}H2)}} gives W(CO)3(PiPr3)2(η2-H2)

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

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

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

  • {{chem2|auto=yes|CH3CH2CH3CBrFCIClCH3}} gives CH3CH2CH3CBrFCIClCH3

  • {{chem2|NH2RCHCO2H <-> NH3+RCHCO2−}} gives NH2RCHCO2H ⇌ NH+3RCHCO2
