Beschreibung:
  • A neodymium borosilicate, Mg 2Nd 13(BO 3) 8(SiO 4) 4(OH) 3 (MgNdBSi-1), was obtained from a high-temperature (1400 °C), solid-state reaction under high-pressure conditions (4.5 GPa). MgNdBSi-1 contains six different types of Nd 3+ coordination environments with three different ligands: BO 3, SiO 4, and OH groups. Mg 2+ cations are only bond to BO 3 groups and form porous two-dimensional layers based on 12-membered ring fragments. Surprisingly, the OH groups are retained at high temperature and reside at the center of Mg-BO 3 rings. © 2012 American Chemical Society.
