丙酸铜是铜(II)的丙酸盐,化学式为Cu(CH3CH2COO)2,或简写为Cu(prop)2

结构

丙酸铜晶体属三斜晶系晶格参数a=9.58Å, b=5.22Å, c=8.55Å;α=105°55′, β=92°33′, γ=91°7′。[1]

丙酸铜二水合物属单斜晶系,晶格参数a=18.18Å, b=15.30Å, c=10.93Å;α=90.00°, β=15.30°, γ=10.93°。[2]

化学性质

丙酸铜在240~350℃分解:[2]

3 Cu(CH3CH2COO)2 → Cu + Cu2O + 3 CH3C(=O)CH2CH2CH3 + 3 CO2

分解出的灼热的氧化亚铜会在空气中氧化为黑色的氧化铜
