Webb11 maj 2024 · The ionic radii are calculated from the internuclear distances in ionic crystals by assuming the radius of one ion. Though the ionic radii do not remain constant in different crystals, the variations are small, and the radii (in pm) are found to be as: r (Na) = r (Li) + 25 ± 3 r (Cl) = r (F) + 50 ± 4 r (K) = r (Na) + 32 ± 2 r (Br) = r (Cl) + 16 ± 2 WebbReaction of lanthanum with Hg(C6F5)2 and bulky N,N′-bis(2,6-diisopropylphenyl)formamidine (HDippForm) in tetrahydrofuran gives [LaF{DippForm}2(THF)] with a rare terminal Ln–F bond, and a high yield of a novel functionalised formamidine, DippForm((CH2)4OC6F4H-o).
