tructure
β-BiF3 has the YF3 structure where the bismuth atom has distorted 9 coordination, tricapped trigonal prism. Wells A.F. (1984) "Structural Inorganic Chemistry" 5th edition Oxford Science Publications ISBN 0-19-855370-6 ] This structure is generally considered to be ionic, and contrasts with fluorides of the lighter members of group 5,
phosphorus trifluoride ,PF3,arsenic trifluoride , AsF3 andantimony trifluoride , SbF3 where MX3 molecular units are present in the solid.References
