2-Hy-droxy-ethyl-ammonium iodide.

Area of Science:

• Crystallography
• Solid-state chemistry
• Hydrogen bonding

Background:

• Hydrogen bonds are crucial in determining crystal structures.
• Layered structures are common motifs in crystalline materials.
• Understanding intermolecular interactions aids in predicting material properties.

Purpose of the Study:

• To elucidate the crystal structure of the title salt (C2H8NO(+)·I(-)).
• To identify and characterize the hydrogen bonding network within the crystal lattice.
• To describe the resulting supramolecular architecture.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the atomic arrangement.
• Analysis of intermolecular distances and angles confirmed hydrogen bond formation.
• Crystal structure visualization tools were used to illustrate the packing.

Main Results:

• The crystal structure of the title salt, C2H8NO(+)·I(-) , was successfully determined.
• N-H⋯O, N-H⋯I, and O-H⋯I hydrogen bonds were identified as the primary intermolecular forces.
• These hydrogen bonds facilitate the formation of layered structures that are staggered along the c axis.

Conclusions:

• The hydrogen bonding network dictates the formation of a specific layered crystal architecture.
• The staggered arrangement along the c axis is a direct consequence of the observed hydrogen bond geometry.
• This study provides detailed insights into the structure-property relationships governed by hydrogen bonding in ionic salts.
