Summary
This study details the crystal structure of a hydrated 4,4-bipyridine compound. It reveals how bipyridine molecules and water form hydrogen-bonded sheets and chains, offering insights into supramolecular assembly.
Area of Science:
- Crystallography
- Supramolecular Chemistry
- Materials Science
Background:
- 4,4-bipyridine is a versatile organic compound with applications in coordination chemistry and materials science.
- Understanding the solid-state structure of its hydrates is crucial for predicting and controlling its properties.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C10H8N2.2H2O.
- To investigate the hydrogen bonding interactions and molecular arrangement in the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the three-dimensional crystal structure.
- Analysis of hydrogen bonding networks (O-H...N and O-H...O) was performed.
Main Results:
- The crystal structure features stacked 4,4-bipyridine molecules along the b axis.
- These stacks are interconnected by O-H...N and O-H...O hydrogen bonds, forming sheets parallel to the (100) plane.
- Chains of hydrogen-bonded water molecules are observed between the bipyridine stacks, involving four crystallographically independent water molecules and two independent bipyridine molecules.
Conclusions:
- The study provides a detailed description of the hydrogen-bonding network in hydrated 4,4-bipyridine.
- The findings contribute to the understanding of crystal engineering and the self-assembly of organic-inorganic hybrid materials.
