Summary
This study characterizes the crystal structure of a compound, revealing planar six-membered rings and N-H...O hydrogen bonds linking cations and anions in chains. These findings provide insights into the molecular arrangement and bonding within this crystalline material.
Area of Science:
- Crystallography
- Solid-state chemistry
- Materials science
Background:
- Understanding the precise arrangement of atoms and molecules in crystalline solids is fundamental to predicting and controlling material properties.
- Hydrogen bonding plays a crucial role in supramolecular assembly and the stability of crystal structures.
Purpose of the Study:
- To determine the crystal structure of the compound C5H7N2+.C7H5O3-.
- To elucidate the bonding interactions and structural motifs present in the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction analysis was performed using graphite-monochromated CuK alpha radiation.
- The crystal structure was solved and refined to a final R value of 0.050 for 1116 reflections.
Main Results:
- The compound crystallizes in the orthorhombic system with space group Pbca.
- Unit cell parameters are a = 15.928(5), b = 11.830(5), c = 11.768(6) A.
- Both six-membered rings within the structure are planar.
- The crystal structure features chains formed by the linkage of cations and anions via N-H...O hydrogen bonds along the [001] direction.
Conclusions:
- The crystal structure of C5H7N2+.C7H5O3- has been fully characterized.
- The observed hydrogen bonding network dictates the one-dimensional chain formation, influencing the overall crystal packing and properties.
