Similarly, the structure of Ba7(BO3)3GeO4Br is composed of a 3D Ba(1,4, 5)-based framework with tunnels viewed along b axis, in which the BrBa(2, 6)3 chains are located (Fig. 3a). In addition, {[Ba(3)O4(GeO4)]2} double chains and isolated BO3 triangles fill in the framework to form its 3D network structure (Fig. 3b and c). The {[Ba(3)O4(GeO4)]2} double chains are built of isolated GeO4 tetrahedra and Ba(3)O10 polyhedra. H@GDV7%7@`TN970JLJXIDUP.png  O%$JQT(1Q(_RE}7TQYM0]}Y.png  B0HWTEJ$DTOBPN~BL}0`3YI.png |
