Nkọwa: α-BiF3 nwere cubic crystalline Ọdịdị (Pearson akara cF16, ohere otu Fm-3m, No. 225). BiF3 bụ prototype maka DO3 Ọdịdị, nke na-adiaha site ọtụtụ intermetallics, gụnyere Mg3Pr, Cu3Sb, Fe3Si, na AlFe3, nakwa dị ka site na hydride LaH3.0. The unit cell bụ ihu centered cubic na Bi na ihu n'etiti na vertices, na F na octahedral saịtị (n'etiti-edges, center), na tetrahedral saịtị (n'etiti nke 8 sub cubes) - otú ahụ ka oge gboo cell nwere 4 na 12 F. Alternatively, na unit cell shifted (1/4,1/4) na cell ihu nwere ike na-ewere dị ka a siri ike cubic na trifluoride ion, na trifluoride ion, na trifluoride ion jupụtara fcc, na nkuku, na trifluoride ion, na trifluoride ion.
