The structures of anions in two different salts, [Et4N]2[InCl5] and [NH3(CH2)5NH3][TiCl5].


For [Et4N]2[InCl5], the anion is [InCl5]2-. Indium (In) typically forms a trigonal bipyramidal structure with five chloride ions because it can accommodate five ligands around it.


For [NH3(CH2)5NH3][TiCl5], the anion is [TiCl5]2-. Titanium (Ti) in the +4 oxidation state usually forms a square pyramidal structure with five ligands due to its d^0 configuration.


Therefore, the correct answer is:


Option A: Trigonal bipyramidal and square pyramidal.

Structure of [Et4N]2[InCI5] and [NH3(CH2)5(NH3)][TiCI5]

Trigonal Bipyramidal Structure of [Et4N]2[InCI5]

- The anion [InCI5] has a trigonal bipyramidal structure.
- It consists of five chlorine atoms and an indium atom in the center.
- The chlorine atoms are arranged in a trigonal plane, and the other two atoms form axial positions.
- The trigonal plane is formed by three equatorial lone pairs of electrons and two axial chlorine atoms.
- The shape of the anion is trigonal bipyramidal because it has one central atom and five surrounding atoms, which are arranged in a trigonal plane and two axial positions, respectively.

Square Pyramidal Structure of [NH3(CH2)5(NH3)][TiCI5]

- The anion [TiCI5] has a square pyramidal structure.
- It consists of five chlorine atoms and a titanium atom in the center.
- The chlorine atoms are arranged in a square plane, and the other atom forms an axial position.
- The square plane is formed by four equatorial chlorine atoms, and the axial position is occupied by the fifth chlorine atom.
- The shape of the anion is square pyramidal because it has one central atom and five surrounding atoms, which are arranged in a square plane and one axial position, respectively.

Both Anions have Square Pyramidal Structure

- The correct answer is option 'C' because both anions have a square pyramidal structure.
- The anion [Et4N]2[InCI5] has a trigonal bipyramidal structure; however, it is a cation, not an anion.
- The anion [NH3(CH2)5(NH3)][TiCI5] has a square pyramidal structure, as discussed above.
- Therefore, the anions in the given compounds have different structures, and option 'C' is the correct answer.
