^ 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)
5CH
3
{{chem2|Fe3S2(CO)9}} gives Fe
3S
2(CO)
9
{{chem2|C_{''n''}H_{2''n''+2}|}} gives C
nH
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
2O → 2 H
2SO
4
{{chem2|2S + 3O2 + 2H2O -> 2H2SO4}} gives 2S + 3O
2 + 2H
2O → 2H
2SO
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
2O
(g)
{{chem2|NH2RCHCO2H <-> NH3+RCHCO2-}} gives NH
2RCHCO
2H ⇌ NH+
3RCHCO−
2

Hapticity and mu:

{{chem2|W(CO)3(PiPr3)2(\h{2}\-H2)}} gives W(CO)
3(PiPr
3)
2(η²−-H
2)
{{chem2|auto=yes|W(CO)3(PiPr3)2(\h{2}\-H2)}} gives W(C O)
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 C H
3CH
2CH
3CBr FCI ClCH
3
