Synthesis, crystal structure and EPR spectra of tetraaquabis(methylisonicotinate) copper(II) disaccharinate single crystal
Özet
The crystal structure of the [Cu(mein)(2)(H2O)(4)]center dot(sac)(2) complex (mein: methylisonicotinate, sac: saccharine) was investigated by single crystal X-ray diffraction technique. The vibrational spectrum was also discussed in relation with the other compounds containing methylisonicotinate and saccharinate complexes. The EPR spectra of [Cu(mein)(2)(H2O)(4)]center dot(sac)(2) single crystal have been studied in the temperature range between 113 and 300 K in three mutually perpendicular planes and exhibit two sets of four hyper-fine lines of Cu2+ ion. The ground state wave function of the Cu2+ ion is an admixture of d(x2-y2) and d(z2) states. (C) 2011 Elsevier B. V. All rights reserved.
