Background:

Understanding the supramolecular assembly of organic-inorganic hybrid materials is crucial for designing novel functional compounds.
Hexachlorotin(IV) complexes offer a versatile platform for exploring coordination chemistry and crystal engineering.

Purpose of the Study:

To elucidate the crystal structure of bis(benzylammonium) hexachlorotin(IV).
To investigate the intermolecular interactions governing the self-assembly of this hybrid material.

Main Methods:

Single-crystal X-ray diffraction analysis was employed to determine the atomic arrangement.
Analysis of hydrogen bonding and pi-pi stacking interactions was performed.

Main Results:

The crystal structure consists of alternating ionic ([SnCl(6)](2-)) and hydrocarbon ((C(7)H(7)NH(3))+) layers.
Two distinct benzyl groups within the hydrocarbon layers exhibit aromatic pi-pi stacking.
Ammonium groups form extensive hydrogen bonds (normal, bifurcated, trifurcated) with the [SnCl(6)](2-) octahedra.

Conclusions:

The crystal packing is dictated by a combination of electrostatic interactions, hydrogen bonding, and van der Waals forces.
The observed supramolecular architecture highlights the interplay between organic cations and inorganic anions.
This study provides insights into the structural features of benzylammonium hexachlorotin(IV) salts.
