Template:Chem2/doc

chem2 is a template used to format a chemical formula or equation.

Use
 ^ 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),   or.

Formulas (without charge) are just written. Eg.:
 * gives CH3(CH2)5CH3
 * gives Fe3S2(CO)9
 * gives C_{n}H_{2n+2}

Charges are written inside parenthesis, otherwise it's treated as +1 or −1, e.g.:
 * gives Na+
 * gives O2- but can be written as  too.
 * gives SO4(2-)
 * gives S19(2+)

Chemical equations can be written too. E.g.: The arrows can be written as  or just. All characters (and unicode markup) are valid input except, = (Mediawiki use it),   and   (endash etc.)
 * gives 2 S + 3 O2 + 2 H2O -> 2 H2SO4
 * gives 2S + 3O2 + 2H2O -> 2H2SO4
 * gives 2 H2_{(g)} + O2_{(g)} -> 2H2O_{(g)}
 * gives NH2RCHCO2H <-> NH3+RCHCO2-

Hapticity and mu:
 * gives W(CO)3(PiPr3)2(\h{2}H2)
 * gives W(CO)3(PiPr3)2(\h{2}H2)

Links: Use or ordinary wiki link (  and  ), e.g.:
 * gives FeCl3
 * gives 3H2 + 2N2 <-> 2NH3

Auto links: Automatic link elements: Use (e.g.  ):
 * gives CH3CH2CH3CBrFCIClCH3
