BiF3 ne prototype ga DO3 tsarin, wanda aka soma da dama intermetallics, ciki har da Mg3Pr, Cu3Sb, Fe3Si, da kuma AlFe3, kazalika da hydride LaH3.0. A naúrar cell ne fuska-tsakiya cubic da Bi a fuska cibiyoyin da vertices, da kuma F a octahedral site (mid-gefen, cibiyar), da kuma tetrahedral sites (cibiyoyin na 8 sub-gefen) - haka na farko cell ƙunshi 4 da kuma 12 F. A madadin, tare da naúrar cell canjawa (1/4,1/4) da cell fuska za a iya daukarsa a matsayin mai f, da kuma kusurwa, cike da kusurwa, da kuma kusurwa, da kuma kusurwa, cike da F, da kuma AlFe3.0 hydride. Wannan naúrar cell ne fuska-tsakiya cubic da Bi a fuska cibiyoyin da vertices, da kuma F a octahedral site (mid-gefen, cibiyar), da kuma tetrahedral sites (cibiyoyin na 8 sub-gefen) -
