Summary
The crystal structure of lead tartrate was determined using X-ray powder diffraction. Lead ions coordinate with nine oxygen atoms, forming a 3D network via lead-oxygen bonds.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Materials Science
Background:
- Lead tartrate is a salt with potential applications in various chemical processes.
- Understanding its crystal structure is crucial for predicting its properties and reactivity.
Purpose of the Study:
- To elucidate the crystal structure of lead tartrate.
- To determine the coordination environment of lead ions and the bonding interactions within the material.
Main Methods:
- X-ray powder diffraction (XRPD) was employed to collect structural data.
- Rietveld refinement was used to solve and refine the crystal structure.
Main Results:
- The crystal structure of lead tartrate, Pb(2+).C(4)H(4)O(6)(2-), was successfully solved.
- Lead cations (Pb(2+)) were found to exhibit ninefold coordination.
- Tartrate groups act as ligands, linking lead ions through lead-oxygen (Pb.O) contacts.
- A robust three-dimensional (3D) network structure was identified.
Conclusions:
- The detailed crystal structure of lead tartrate provides fundamental insights into its solid-state chemistry.
- The observed ninefold coordination of lead and the 3D network structure are key features influencing its material properties.
