Hydrogen fumarate anions in crystals form one-dimensional chains via O-H.O hydrogen bonding. This structural arrangement reveals specific bonding patterns and site characteristics within the crystal lattice.

Area of Science:

Crystallography
Solid-state chemistry

Background:

Hydrogen bonding plays a crucial role in determining crystal structures.
Understanding supramolecular arrangements is key to predicting material properties.

Purpose of the Study:

To elucidate the crystal structure of the title compound.
To investigate the hydrogen bonding interactions of hydrogen fumarate anions.

Main Methods:

Single-crystal X-ray diffraction analysis.
Analysis of hydrogen bonding networks.

Main Results:

The hydrogen fumarate anions form one-dimensional chains.
Hydrogen bonding occurs along the c and (a+b)/2 directions.
Three distinct sites for the hydrogen fumarate anion were identified, with two possessing an inversion center.
