Ko te BiF3 ko te tauira mo te hanganga DO3, i tangohia e te maha intermetallics, tae atu Mg3Pr, Cu3Sb, Fe3Si, me AlFe3, me te hydride LaH3.0. Ko te pūtau waeine he kanohi ki te pokapū ki te Bi i te mata pokapū me ngā tihi, me te F i te pae octahedral (mid-edges, pokapū), me ngā pae tetrahedral (pokapū o te 8 sub-pae) - na te pūtau taketake kei roto i te 4 me te 12 F. Ka taea te hurihia te pūtau waeine (1/4,1/4) te kanohi o te pūtau ki te fcc, te kokonga, me te kokonga, ki tonu i te kokonga, me te kokonga, me te kokonga, me te F3Si, me te AlFe3, me te hydride LaH3.0.
