Abstract
Single crystals of Nd4Mn(SiO4)3O have been prepared by a Bi2O3 flux in closed copper tubes. The colourless crystals show hexagonal symmetry, space group C6h 2—P63/m, a = 9,4986(9), c = 6,944(2) Å, Z = 2. Nd4Mn(SiO4)3O crystallizes in the Apatite structure and shows Nd3+ and Mn2+ with partly statistical distribution. As a consequence of this, O(2) and O(4) are occupying split positions.Keywords
