The first entirely pentavalent uranium borate, Na 2 (UO 2 )(BO 3 ), was synthesized under mild hydrothermal conditions. The single-crystal structure was solved in the orthorhombic space group Cmcm with a = 10.0472(3) Å, b = 6.5942(2) Å, and c = 6.9569(2) Å. Magnetic susceptibility measurements revealed an antiferromagnetic transition at 12 K and an effective magnetic moment of 2.33 μ B . Density functional theory calculations indicated dynamic stability of the structure above 0 K.
