Summary
This study describes a novel organic-inorganic hybrid material featuring extended lead-iodide chains. The structure is stabilized by pentane-1,5-diammonium cations through hydrogen bonding.
Area of Science:
- Materials Science
- Crystallography
- Inorganic Chemistry
Background:
- Organic-inorganic hybrid materials offer unique properties.
- Lead-iodide based compounds are of interest for their structural diversity.
Purpose of the Study:
- To characterize the crystal structure of the novel organic-inorganic hybrid compound [(NH(3)C(5)H(10)NH(3))(2)[Pb(3)I(10)]](n).
- To investigate the structural features and bonding interactions within this hybrid material.
Main Methods:
- Single-crystal X-ray diffraction.
- Analysis of crystallographic data to determine atomic positions and coordination environments.
Main Results:
- The compound crystallizes as an organic-inorganic hybrid with extended [Pb(3)I(10)](n)(4n-) chains along the [111] direction.
- Two independent lead atoms are present, both octahedrally coordinated by six iodide ions.
- Face- and edge-sharing between lead and iodide ions form the inorganic chains.
- Pentane-1,5-diammonium cations occupy channels and form N-H.I hydrogen bonds with the inorganic chains.
Conclusions:
- The crystal structure reveals a unique arrangement of inorganic chains and organic counter-ions.
- Hydrogen bonding plays a crucial role in stabilizing the overall hybrid structure.
- This work contributes to the understanding of lead-iodide based organic-inorganic materials.
