Structure & Formula
It has the chemical formula Ba(C2H3O2)2. This compound is also known as acetic acid and barium salt. The 2D structure of the compound is displayed below.

The compound has the IUPAC name as barium(2+) diacetate.
Preparation
Barium acetate is produced by the reaction of acetic acid with barium carbonate,
BaCO3 + 2CH3COOH → (CH3COO)2Ba + CO2 + H2O
This reaction takes place in solution and the desired product crystallizes out.
Barium sulfide can also be used instead of barium carbonate to obtain crystallized barium acetate,
BaS + 2CH3COOH → (CH3COO)2Ba + H2S
