Anhydrous neodymium(III) acetate, Nd(OAc) 3 was obtained as light purple single crystals by direct oxidation of neodymium metal with malonic acid in a glass ampoule at 180 °C. It crystallizes with the monoclinic space group P 2 1 / a (no. 14) with a = 2201.7(2), b = 1850.0(1), c = 2419.0(3) pm, β = 96.127(8)°, V = 9796.8(1)·10 6 ·pm 3 , Z = 40 [Nd(OAc) 3 ], R 1 = 0.0430 [I 0 > 2σ(I 0 )]. Most of the Nd 3+ cations are coordinated by nine (or eight) oxygen atoms of acetate ligands which bridge these polyhedra to slightly waved layers which are stacked in the [010] direction.
