Abstract
A novel tripodal ligand with three different arms, viz., pyridine, phenol and an oxime and its copper(II) complex were synthesised. The X-ray crystal structure of the compound reveals that it is a dinuclear complex consisting of two copper(II) ions doubly bridged by two oximato groups in a trans arrangement. The complex contains unusual cis-axially coordinated phenolates as well as a novel interligand, intramolecular phenolate-phenol hydrogen bond. Variable-temperature magnetic susceptibility measurements revealed that the two copper(II) centers are strongly antiferromagnetically coupled, with the exchange coupling constant -2J = 800(42) cm(-1) (H= -2J (S) over cap (1).(S) over cap (2)) for the two interacting S = 1/2 centres. The complex yields an H-1 NMR spectrum in CD3CN solution at room temperature, with relatively sharp signals and rather small hyperfine shifts, evidencing that the antiferromagnetically coupled dinuclear core is maintained in solution.
