Among the following pairs in which the two species are not isostructur...
Explanation:
Isostructural species are those that have the same shape and bond angle. The given pairs are:

a) IO3- and XeO3
Both have trigonal bipyramidal shape and bond angle of 90° and 120°. Hence, they are isostructural.

b) BH4- and NH4+
Both have tetrahedral shape and bond angle of 109.5°. Hence, they are isostructural.

c) PF6- and SF6
Both have octahedral shape and bond angle of 90° and 180°. Hence, they are isostructural.

d) SiF4 and SF4
SiF4 has a tetrahedral shape and bond angle of 109.5°. SF4 has a seesaw shape with bond angle of <90° and=""><120°. hence,="" they="" are="" not="">

Therefore, the correct answer is option D.
