Lead(II) perchlorate is a chemical compound with the formula Pb(ClO4)2·xH2O, where is x is 0,1, or 3.

The anhydrous salt, Pb(ClO4)2, is produced by heating the trihydrate to 120 °C under water-free conditions over phosphorus pentoxide.

[1][2] The monohydrate is produced by only partially dehydrating the trihydrate, and this salt undergoes hydrolysis at 103 °C.

[3] The solution of anhydrous lead(II) perchlorate in methanol is explosive.

[1] Lead perchlorate has a high nucleon density, making it a viable detector for hypothetical proton decay.
