Mercury (II) acetate: Hg(CH3COO)2
Formula: (CH3COO)3Au
(CH3COO)2Cu.H2O
Co(C2H3O2)2
That's copper acetate. Copper is Cu, and the acetate polyatomic ion is C2H3O2, although copper's most common valence state is +2, so the more likely formula would be Cu(C2H3O2)2. (acetate has a -1 charge.)
Mercury (II) acetate: Hg(CH3COO)2
Molybdenum(II) acetate is a coordination compound with the formula Mo2(O2CCH3)4
The formula for iron(II) acetate is to my knowledge Fe(C2H3O2)2. And iron(III) acetate is to my knowledge Fe(C2H3O2)3.
Formula: (CH3COO)3Au
The chemical formula of iron(II0 acetate is Fe(CH3COO)2.
Pb(C2H3O2)2
(CH3COO)2Cu.H2O
Co(C2H3O2)2
That's copper acetate. Copper is Cu, and the acetate polyatomic ion is C2H3O2, although copper's most common valence state is +2, so the more likely formula would be Cu(C2H3O2)2. (acetate has a -1 charge.)
Stannous = tin(II). Stannic = tin(IV). So stannous acetate is Sn(C2H3O2)2.
C4H6NiO4 Ni(C2H3O2)2 for nikel (II) acetate
The name of the compound Zn C2H3O22 or Zn (CH3COO)2 is Zinc acetate.
