Syntheses of lanthanide bromide complexes from oxides and the crystal structures of [LnBr3(DME)2] (Ln = Pr, Nd, Sm, Eu), [LnBr3(THF)4] (Ln = Pr, Sm) and [EuBr2(THF)5][EuBr4(THF)2]

lanthanide atom in the crystalstructures of lanthanidecomplexes [LnBr3(DME)2] (Ln = Pr (1), Nd (2), Sm (3), Eu (4)). Crystallization from THF resulted in two types of complexes, molecular [LnBr3(THF)4] (Ln = Pr (5), Sm (6)) and ionic [EuBr2(THF)5][EuBr4(THF)2] (7). Complexes 1, 4, 5 and 7 are the first crystallographically characterized water-free complexes of praseodymium or europium tribromides.
