In-situ preparation of macrocyclic complexes of dioxomolybdenum(VI) involving a heterocyclic precursor

Abstract

Dioxomolybdenum(VI) complexes [MoO₂(mac)](acac)₂ (where mac = tetraazamacrocyclic ligands derived from condensation of thenil with 1,2-diaminobenzene or 2,3-diaminopyridine and their reaction with β-diketones) have been prepared using dioxometal ion as kinetic template. Tentative structures of the complexes have been proposed on the basis of elemental analysis, infrared, and electronic data. All the dioxomolybdenum(VI) complexes are six-coordinate octahedral ones.

Keywords:

• Dioxomolybdenum(VI)
• Kinetic template
• Macrocyclic complexes
