制备

在1 N高氯酸介质中，将高氯酸汞加入至四氯合铂(II)酸钾溶液中搅拌，再加入高氯酸银，过滤后得到含有橙黄色的[Pt(H₂O)₄]²⁺离子，在碱性条件下将乙酰丙酮的碱性溶液加至上述Pt(II)溶液中，产生暗灰色沉淀，搅动下变为黄色，即乙酰丙酮铂(II)。^[2]

[Pt(H₂O)₄]²⁺ + 2 H(acac) + 2 OH⁻ → Pt(acac)₂ + 6 H₂O

它也可由六氟合铂(IV)酸在含有乙醇的高氯酸中与乙酰丙酮反应得到。^[3]

性质

乙酰丙酮铂(II)可以和其它配位能力更强的配体反应，得到新的配合物。^[4][5]它和乙酰丙酮银混合，可以增加乙酰丙酮银的热稳定性。^[6]
