This study details the crystal structure of a rubidium 3,5-dinitro-salicylate compound. The research reveals a 3D framework built from rubidium cations and dinitro-salicylate ligands, featuring zigzag chains and π-π stacking.
Area of Science:
- Inorganic Chemistry
- Crystal Engineering
- Coordination Chemistry
Background:
- Rubidium salts of organic acids are explored for their unique structural properties.
- Salicylate derivatives, particularly those with nitro groups, offer diverse coordination possibilities.
- Understanding metal-organic frameworks is crucial for materials science.
Purpose of the Study:
- To elucidate the crystal structure of the rubidium 3,5-dinitro-salicylate compound.
- To investigate the coordination environment of the rubidium cation.
- To characterize the intermolecular interactions within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the crystal structure.
- The asymmetric unit was analyzed to identify the rubidium cation and the 3,5-dinitro-salicylate ligand.
- Coordination geometry and intermolecular interactions (hydrogen bonding, π-π stacking) were examined.
Main Results:
- The asymmetric unit contains one Rb(+) cation and one 3,5-dinitro-salicylate ligand.
- The Rb(+) cation exhibits 10-coordination by oxygen atoms from eight salicylate anions.
- A 3D framework is formed via zigzag chains along the b-axis, stabilized by phenyl group linkages, hydrogen bonds, and π-π stacking (3.6755(7) Å).
Conclusions:
- The crystal structure of [Rb(C(7)H(3)N(2)O(7))](n) has been successfully determined.
- The coordination and assembly of the rubidium cation and dinitro-salicylate ligand result in a robust 3D framework.
- The presence of hydrogen bonding and π-π stacking interactions plays a significant role in stabilizing the crystal structure.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
