Crystal structure of the solid solution Ba_8.35Pb_0.65(B₃O₆)₆

Abstract

The fundamental building units of Ba8.35Pb0.65(B3O6)6 are isolated planar B3O6 anionic groups, which are distributed layer upon layer perpendicular to [001], with (Pb/Ba) and Ba sites alternately located between the B3O6 sheets.

Ba10LuB18O32F13: the first example of borate in the Lu–B–O–F system with the unprecedented FBB [B9O22]

“…Several FBB categories can be symbolized based on the number of B atoms, ranging from 3 to 18, in these compounds, as follows. (1) The FBBs in Ba 8.35 Pb 0.65 (B 3 O 6 ) 6 , 39 Ba 8.019 Pb 0.981 B 18 O 36 , 40 and Pb 1.13 Ba 7.87 B 18 O 36 41 are the same [B 3 O 6 ] (3:[(3Δ)]) groups. (2) The FBBs with nine B atoms have different connection models and various styles.…”
