The preparation of copper‐tetrasodium trimetaphosphate tetrahydrate: Na 4 Cu(P 3 O 9 ) 2 · 4H 2 O is described. This salt is the first example of the occurence of Cu II in a trimetaphosphate. The triclinic unit cell has the dimensions a = 7.907(5), b = 8.364(5), c = 7.122(5) Å, α = 102.46(5), β = 97.89(5), γ = 84.04(5)°. Crystal structure has been solved by using 2019 independent reflexions with a final R value 0.017. Both copper and sodium atoms are in octahedral coordination. NaO 6 octahedra form ribbons running in (011) planes. These ribbons are interconnected by CuO 6 octahedra as to form a three dimensional network. Hydrogen atoms have been located and refined. The hydrogen bond scheme is described.
