“…[16][17][18][19][20] Metal tellurites can also display plentiful structure types because the polar oxyanions can join together by condensation to generate 0D clusters, [21][22][23] 1D chains, [24][25][26][27] 2D layers 28,29 and even 3D frameworks. 30,31 Fluorine, as the most electronegative element, could replace oxygen ligands due to their similar ionic radii. [32][33][34] When fluorine atoms are introduced into oxide compounds, fluoride compounds often can display excellent comprehensive performance and abundant structure types, [35][36][37][38] such as RbTeMo 2 O 8 F (27 × KDP, 3.63 eV), 39 Ba(MoO 2 F) 2 (TeO 3 ) 2 (7.8 × KDP, 2.96 eV), 40 and BaF 2 TeF 2 (OH) 2 (3 × KDP, 5.9 eV) 41 in metal tellurites.…”
