Berger, T. and Range, Klaus-Jürgen (1996) High-pressure synthesis and structure refinement of strontium Danburite, SrB2Si2O8. ZEITSCHRIFT FUR NATURFORSCHUNG SECTION B-A JOURNAL OF CHEMICAL SCIENCES, 51 (2). pp. 172-174. ISSN 0932-0776, 1865-7117

Single crystals of strontium danburite, SrB2Si2O8, were found after high-pressure treatment of SrSiO3/SiO2/Al2O3 mixtures at 40 kbar and 1400 degrees C, obviously formed by an unwanted side reaction with the boron oxide-containing boron nitride capsules used. The crystals are orthorhombic, space group Pnma, with a = 8.1891(5), b = 7.9311(6), c = 8.9284(5) Angstrom and Z = 4. The structure was refined to R = 0.031, R(w) = 0.028 for 590 independent, absorption-corrected reflections. SrB2Si2O8 is isostructural with danburite (CaB2Si2O8). The structure comprises a tetrahedral framework of ordered B2O7 and Si2O7 groups which contains Sr in irregular coordination.
