Formulas, charges, equations
[uredi kodo]Formulas (without charge) are just written:
{{chem2|CH3(CH2)5CH3}}→ CH3(CH2)5CH3{{chem2|Fe3S2(CO)9}}→ Fe3S2(CO)9{{chem2|C_{''n''}H_{2''n''+2}|}}→ CnH2n+2
Charges are written inside parentheses:
{{chem2|SO4(2-)}}→ SO2−4{{chem2|S19(2+)}}→ S2+19
Charges +1 and −1 can be written plain:
{{chem2|Na+}}→ Na+{{chem2|O2-}}→ O−2
- equals
{{chem2|O2(-)}}
Chemical equations:
{{chem2|2 S + 3 O2 + 2 H2O -> 2 H2SO4}}→ 2 S + 3 O2 + 2 H2O → 2 H2SO4{{chem2|2S + 3O2 + 2H2O -> 2H2SO4}}→ 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)}|}}→ 2 H2(g) + O2(g) → 2H2O(g){{chem2|NH2RCHCO2H <-> NH3+RCHCO2-}}→ NH2RCHCO2H ⇌ NH+3RCHCO−2
Hapticity and mu:
{{chem2|W(CO)3(PiPr3)2(\h{2}H2)}}→ W(CO)3(PiPr3)2(η2-H2){{chem2|auto=yes|W(CO)3(PiPr3)2(\h{2}H2)}}→ W(CO)3(PiPr3)2(η2-H2)
Wikilinks
[uredi kodo]Whole formula link
[uredi kodo]Link the whole formula with |link=<wiki pagename>:
{{chem2|FeCl3|link=Iron(III) chloride}}→ FeCl3
Or use wikilink brackets in input like [[ammonia|NH3]]:
Link each element (C, Hg) and generic element code (R, X)
[uredi kodo]- Use
|auto=yesto link each element symbol once, as well as some others such as Ph
Link functional groups
[uredi kodo]Some common groups are recognized and linked if you wikilink them using [[ ]]
{{chem2|R\-[[COOH]]}}→ R-COOH{{chem2|[[CH3]]C[[R]]2[[I]]}}→ CH3CR2I- In particular H2O links to water of crystallization in
{{chem2|CuSO4 * 5 [[H2O]]}}→ CuSO4 · 5 H2O, because a link to water is generally unnecessary.
You can link to any article even if chem2 is unaware of it:!-- same as |link=... then -->
{{chem2|[[C6H5NH2]]}}→ C6H5NH2
To change the default link:
{{chem2|[[water|H2O]]}}→ H2O
