This is an alkoxide, sodium ethoxide.

#H_3C-CH_2O^(-)Na^+# is the sodium salt of ethanol, #H_3C-CH_2OH#. It can be formed directly by the action of sodium metal on ethanol:

#Na(s) + HOCH_2CH_3 rarr Na^(+)""^(-)OCH_2CH_3 + 1/2H_2(g) uarr#

This is precisley akin to the formation of sodium hydroxide and hydrogen gas from water and the alkali metal.
