Abstract

Single crystals of MnUO₄, FeUO₄, and NiU₂O₆ were grown for the first time. The use of chloride fluxes facilitated the crystal growth. MnUO₄, a hexavalent uranium compound, crystallizes in the orthorhombic space group, Imma, with a = 6.6421(19) Å, b = 6.978(2) Å, and c = 6.748(2) Å, and exhibits typical uranyl, UO₂²⁺, coordination. FeUO₄ and NiU₂O₆ contain pentavalent uranium and are structurally related, exhibiting three-dimensional connectivity. FeUO₄ crystallizes in the orthorhombic space group, Pbcn, with a = 4.8844(2) Å, b = 11.9328(5) Å, c = 5.1070(2) Å. NiU₂O₆ crystallizes in the trigonal space group, P321, with a = 9.0148(3) Å, c = 5.0144(3) Å.
