Abstract The reaction between Yb(III) nitrate, Ag(I) nitrate, and the diethylenetriamine pentaacetate (dtpa) ligand gives rise to a bimetallic complex. [YbAg2(dtpa)(H2O)]·3H2O is triclinic, space group P-1, with a = 8.768 (3), b = 9.862 (2), c = 13.055 (2) Å, α = 75.40 (1), β = 83.00 (2) and γ = 87.46 (2)°. Each dtpa is coordinated to one ytterbium and six silver atoms. The resulting crystal structure can be described as 2D packing. In the layers, the ytterbium atoms are connected through [Ag(COO)]2 dimers. Strong hydrogen bonds, involving the noncoordinated water molecules, ensure crystal cohesion.
