摘要Crystals of scandium magnesium aluminate, ScAlMgO4, were grown from the melt prepared from stoichiometric quantities of Sc2O3, Al2O3 and MgO. Single-crystal X-ray diffraction indicates that ScAlMgO4 crystallizes in the space group R (3) over bar m with a = b = 3.2506(9) angstrom, c = 25.152(8) angstrom, V = 230.16(11) angstrom(3), Z = 3, F(000) = 234, mu = 2.424 cm(-1), the final R = 0.0381 and wR = 0.1061 for 1874 observed reflections with I > 2 sigma(I). In ScAlMgO4, all Sc atoms are coordinated octahedrally, whereas Al or Mg atoms are forming a tetrahedron, or in a triangular bipyramid if one distant O atom is included. The structure of ScAlMgO4 is characterized by {[AlMgO4](3-)}(infinity)(2) layers parallel to the ab plane, and they are further connected into a 3-dimen-sional framework by Sc atoms via O(1) atoms between the layers.
