Abstract

A compound with the composition Nd(C6F5COO)3· H2O (I) is prepared. Single crystals are grown, and their single crystal XRD analysis of the Nd2(H2O)8(C6F5COO)6]·2H2O (II) compound is performed. The crystals are triclinic: a = 7.693(2) Å, b = 9.394(2) Å, c = 18.203(4) Å, α = 81.91(3)°, β = 84.41(3)°, γ = 88.97(3)°, Z = 1, d x = 2.223 g/cm3. The structure is composed of symmetrical molecules of the binuclear [Nd2(H2O)8(C6F5COO)6] complex and crystallization water molecules. The C6F5COO- ligands are monodentate and tridentate bridging- chelating, which results in a closure of two four-membered chelate cycles NdO2C and a four-membered metal cycle Nd2O2. The NdO9 polyhedron is a distorted one-capped tetragonal antiprism.
