(4-Bromo-2-{[2-(morpholin-4-yl)ethyl-imino]-meth-yl}phenolato)dioxido-vanadium(V)

Area of Science:

• Inorganic Chemistry
• Coordination Chemistry
• Crystallography

Background:

• Vanadium complexes are investigated for diverse applications.
• Schiff base ligands offer versatile coordination environments.
• Understanding metal-ligand interactions is crucial in coordination chemistry.

Purpose of the Study:

• To synthesize and characterize a novel mononuclear dioxidovanadium(V) complex.
• To elucidate the coordination geometry and crystal structure of the complex.
• To investigate intermolecular interactions within the crystal.

Main Methods:

• Synthesis of the vanadium(V) complex using a Schiff base ligand.
• Single-crystal X-ray diffraction analysis to determine molecular and crystal structure.
• Analysis of coordination environment and intermolecular contacts.

Main Results:

• A mononuclear dioxidovanadium(V) complex, [V(C(13)H(16)BrN(2)O(2))O(2)], was successfully synthesized.
• The vanadium(V) center is five-coordinated, adopting a distorted square-pyramidal geometry.
• Weak C-H⋯O interactions and a notable Br⋯Br contact (3.4597(12) Å) were identified in the crystal lattice.

Conclusions:

• The study provides detailed structural insights into a novel vanadium(V) dioxidovanadium complex.
• The coordination chemistry of vanadium with Schiff base ligands is further expanded.
• The presence of specific intermolecular interactions influences the crystal packing.
