Sarcosine Halogenobismuthate Crystal Structures and Spectra

Two halogenobismuthate salts of sarcosine, (SarH)3(Bi2I9) and (SarH)2(BiBr5), were synthesized and characterized. Their crystal structures, IR and Raman spectra, bandgaps, and pyroelectric properties are reported. The dataset was authored by Aram M. Petrosyan and last updated on 2026-05-08.

Use Cases

• Analyze crystal structures based on the reported centrosymmetric and polar space groups.
• Study vibrational spectra based on the IR and Raman data mentioned.
• Investigate optical properties based on the bandgap measurements from powder diffuse reflectance.
• Confirm polar symmetry based on the pyroelectric studies described for compound II.

Strengths

• Contains data on two distinct compounds with different space groups (P21/c and Pna21).
• Includes multiple characterization methods: crystal structure, spectroscopy, bandgap, and pyroelectric studies.
• Reports the first observation of sarcosinium···sarcosinium dimeric cations.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is 333.7 KB, indicating a limited scope.
