Evidence for an Electronically Driven Charge Density Wave in a 1D Metallic MOF

2.2 MB of crystallographic information files (CIF) provide evidence for an electronically driven charge density wave in a series of one-dimensional metallic metal-organic frameworks (LnHOTP, Ln = La, Ce, Pr, Nd, and Sm). The dataset, authored by Jewel Ryu and last updated in May 2026, likely contains structural data from low-temperature and high-pressure crystallography experiments. It shows the modulation wavevector exhibits commensurability lock-in at one-third of the unit cell parameter.

Use Cases

• Analyzing structural modulation patterns based on crystallographic data
• Investigating electronic vs. structural origins of charge density waves based on pressure-sensitive wavevector data
• Comparing quantum state behavior across different lanthanide elements (La, Ce, Pr, Nd, Sm) in MOFs
• Studying commensurability lock-in phenomena based on the wavevector q = 1/3c

Strengths

• Includes crystallographic data for a series of five distinct LnHOTP materials (Ln = La, Ce, Pr, Nd, Sm)
• Provides evidence for an electronic origin of a charge density wave, a rare phenomenon in porous materials
• Contains data from low-temperature and high-pressure experiments, suggesting controlled variable conditions

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is small (2.2 MB), potentially limiting the scope of analysis
