The solubility in the Cu(HCOO) 2 –Sr(HCOO) 2 –H 2 O system has been studied by the method of physico‐chemical analysis at 25 and 50 °C. It has been established that two double salts are formed in the system: CuSr 2 (HCOO) 6 · H 2 O at 25 °C and CuSr(HCOO) 4 · 4 H 2 O at 50 °C. The latter salt has not yet been described in the literature. It has been characterized by X‐ray powder diffraction and DT and TG analysis. CuSr(HCOO) 4 · 4 H 2 O crystallizes in the triclinic system with lattice parameters a = 12.376(6) Å, b = 13.394(4) Å, c = 11.508(6) Å, α = 93.38(3)°, β = 94.01(3)°, γ = 75.04(3)°. Dehydration proceeds in two stages.
