Structural, Spectroscopic and Magnetic Properties of [Cu(1-meim)(4)]center dot 2(PF6)

Abstract

[Cu(1-meim)(4)]center dot 2(PF6) (1-meim: 1-methylimidazole) complex has been synthesized and characterized by EPR, FT-IR, and XRD techniques. The Cu(II) complex crystallizes in the monoclinic system with the space group P2(1)/c. EPR spectrum of [Cu(1-meim)(4)]center dot 2(PF6) powder has been studied at room temperature. The spin Hamiltonian parameters (g and hyperfine values) have been calculated. The results indicate the axial symmetry around the paramagnetic Cu2+ center. The ground state wave function of Cu2+ ion has been constructed. The unpaired electron spends most of its time in dx(2)-y(2) orbital.
