Question

In the case of graphite and TiS2 intercalation compounds, what is the structure possessed by the host crystals?

(a) Spherical structure

(b) Cubical structure

(c) Lamellar structure

(d) Cylindrical structure

The question was posed to me in examination.

This interesting question is from Modification of Existing Structures by Ion Exchange and Intercalation Reactions in chapter Preparative Methods of Solid State Chemistry

Answer 1

Right answer is (c) Lamellar structure

The best explanation: During the intercalation process of graphite and TiS2 compounds, the host crystals possess layer or lamellar structure and the layers are pushed apart as foreign atoms or ions penetrate the interlayer space.
