# Utilizing enantiomerically pure organic spacers for anion-centred clusters in a hybrid inorganic–organic lead-halide crystal

## TL;DR

A new chiral material with a layered structure was synthesized using enantiomerically pure precursors to form bromide-centered clusters.

## Contribution

The use of enantiomerically pure precursors to form anion-centered clusters without bi-functional spacers is novel.

## Key findings

- The material (S-2AH)4[Pb2Br7]Br has a chiral, quasi-2D structure confirmed by single crystal X-ray diffraction.
- Anion-centered clusters are formed in the organic layer due to the steric properties of enantiomerically pure precursors.

## Abstract

In this work, we present structural data of the novel, chiral material (S-2AH)4[Pb2Br7]Br obtained from single crystal X-ray diffraction (SCXRD). This quasi-2D material displays anion-centred clusters within its organic layer, without the need for bi-functional spacers. Instead, the structure is based on the steric properties of the used enantiomerically pure precursors.

We report the synthesis and structure of the novel, chiral material (S-2AH)4[Pb2Br7]Br with a layered structure. Through the use of enantiomerically pure precursors, bromide-centered clusters within the non-polar, organic spacer layer are formed.
