trans-Dioxidotetra-pyridine-rhenium(V) triiodide

Area of Science:

• Inorganic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Rhenium complexes are of interest due to their diverse coordination geometries and potential applications.
• Understanding the structural features of rhenium(V) complexes is crucial for predicting their reactivity and properties.

Purpose of the Study:

• To elucidate the crystal structure and coordination environment of the title rhenium(V) salt, [ReO(2)(C(5)H(5)N)(4)]I(3).
• To investigate intramolecular and intermolecular interactions within the complex.

Main Methods:

• Single-crystal X-ray diffraction was used to determine the molecular and crystal structure.
• Analysis of bond lengths, bond angles, and intermolecular contacts was performed.

Main Results:

• The cation and anion were located on centers of symmetry.
• The rhenium(V) atom exhibited a trans-ReO(2)N(4) octahedral coordination geometry.
• Short intramolecular C-H⋯O contacts were observed within the cation.
• Cations formed layers perpendicular to [100], linked by weak C-H⋯O intermolecular interactions.

Conclusions:

• The crystal structure of [ReO(2)(C(5)H(5)N)(4)]I(3) has been fully characterized.
• The coordination geometry and intermolecular interactions provide insights into the solid-state behavior of this rhenium(V) complex.
