Synthesis, crystal structure, EPR spectra of Cu2+ doped catena-poly[[diaquabis(methylisonicotinate-N)cadmium(II)]-mu-(sulfato-O:O ')] single crystal
Özet
The [Cd(SO4)(C7H7NO2)(2)(H2O)(2)](n) complex has been synthesized and characterized by spectroscopic IR, EPR and X-ray diffraction technique. The compound crystallizes in space group P2(1)/c. The Cd(II) ion is octahedrally coordinated by two aqua, two methylisonicotinate and two sulfate ligands. The methylisonicotinate ligands are N-coordinated, while the sulfate ligands bridge the metal centers, forming the one-dimensional chain structure along the crystallographic [1 0 0] direction. The invidual chains are linked by O-H center dot center dot center dot O hydrogen bonds. The magnetic environments of Cu2+ doped [Cd(SO4)(C7H7NO2)(2)(H2O)(2)](n) complex have been identified by EPR technique. The vibrational spectra of this compound was discussed. (C) 2010 Elsevier B.V.
