Not in JEE Main or NEET syllabus

The radius ratio of CsCl is 0.93. The expected lattice structure is [UP SEE 2008]

(A)Tetrahedral
(B)Square planar
(C)Octahedral
(D)Body centred cubicCorrect

Answer: (D)

Solution

A radius ratio of 0.93 falls in the range 0.732–1.0, which corresponds to 8-fold coordination, i.e. a body-centred-cubic-type arrangement, consistent with the known CsCl structure. It does not fall in
