X-ray powder diffraction study of some cobalt (II) complexes
Published online by Cambridge University Press: 29 February 2012
Abstract
Co(II) complexes with benzoic acid and ternary complexes with ligands benzoic acid and histidine/aspartic acid have been synthesized and characterized using various spectroscopic methods. On the basis of infrared, UV-visible spectra, and magnetic data the complexes were found to be having octahedral polymeric geometry. X-ray powder diffraction results show that the crystal systems of Co(II)-Ben and Co(II)-Ben-Hist complexes are triclinic with lattice constants a=15.58 Å, b=11.92 Å, c=4.33 Å, α=96.08°, β=104.68°, γ=88.46°, and V=774.15 Å3 and a=18.88 Å, b=17.01 Å, c=15.13 Å, α=93.15°, β=89.41°, γ=100.71°, and V=4768.75 Å3, respectively. The Co(II)-Ben-Asp complex is orthorhombic with lattice constants a=21.57 Å, b=15.06 Å, c=11.40 Å. α=β=γ=90°, and V=3703.38 Å3.
