[MPh₄][BPh₄], M = P, As and Sb

M. A. Lloyd and C. P. Brock

Synopsis: The salts [MPh₄][BPh₄], M = P, As and Sb, crystallize in a superlattice of the P-42₁c, Z^' = 1/4, structure known for the molecules MPh₄, M = C, Si, Ge, Sn and Pb. The basic P-42₁c arrangement is retained because the cations and anion are similar in size; the cell is enlarged to accommodate an ionic arrangement that is favorable electrostatically.
