摘要

The thioborates Sr-3(BS3)(2) and Sr-3(B3S6)(2) were prepared from strontium sulfide, amorphous boron and sulfur in solid state reactions at a temperature of 1123 K. In a systematic study on the structural cation influence on this type of ternary compounds, the crystal structures were determined by single crystal X-ray diffraction. Sr3(BS3)2 crystallizes in the monoclinic spacegroup C2/c (No. 15) with a = 10.187(4) Angstrom, b = 6.610(2) Angstrom, c = 15.411(7) Angstrom, beta = 102.24(3)degrees and Z = 4. The crystal structure of Sr-3(B3S6)(2) is trigonal, spacegroup R (3) over bar (Nr. 148), with a = 8.605(1) Angstrom, c = 21.542(4) Angstrom and Z = 3. Sr-3(BS3)(2) contains isolated [BS3](3-) anions with boron in a trigonal-planar coordination. The strontium cations are found between the layers of orthothioborate anions. Sr-3(B3S6)(2) consists of cyclic [B3S6](3-) anions and strontium cations, respectively. [References: 18]
