Abstract
Single crystals of Ag3B5O9 were obtained via high-pressure synthesis at 3GPa and 600°C, using a Walker-type multianvil high-pressure device. Ag3B5O9 crystalizes with a=674.7(2), b=943.5(2), c=1103.5(2)pm, V=0.7025(2)nm3, and Z=4 in the noncentrosymmetric space group P212121 (no. 19). The orthorhombic structure was refined from 3740 independent reflections with R1=0.0496 and wR2=0.587 (all data). It is built up from infinite corner-sharing chains of BO4 tetrahedra along the a axis, which are interconnected by BO3 groups to form a network. In the structure, three crystallographically independent sites are occupied with Ag+ cations exhibiting argentophillic interactions. The synthetic conditions as well as the results of the single crystal structure analysis are presented.
