Anhydrous Neodymium(III) Acetate

Abstract

AbstractAnhydrous 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 P21/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)·106·pm3, Z = 40 [Nd(OAc)3], R1 = 0.0430 [I0 > 2σ(I0)]. Most of the Nd3+ 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.
