SYNTHESIS, PROPERTIES AND CRYSTAL AND MOLECULAR-STRUCTURE OF ISOTHIOCYANATO[N,N-BIS(2-HYDROXYETHYL)GLYCINATO]COPPER(II) MONOHYDRATE

The crystal and molecular structure of the title copper(II) complex was determined by the X-ray diffraction method. The crystal is monoclinic with the space group Cc, Z=4, a= 14.567(2), b= 6.970(1), c = 11.051(2) ) Å, β = 93.67(1)°. Full matrix least-squares refinements have led to a final R value of 0.057 for 1080 reflections. The copper atom is ligated by one carboxylato oxygen atom, two hydroxyl oxygen atoms and one nitrogen atom of the ligand, and one nitrogen atom and one sulfur atom of the isothiocyanate ion. The copper atom is at the center of the typical tetragonal-bipyramidal geometry. One hydroxyl oxygen atom and sulfur atom are at the apical positions and their bond lengths to the copper atom are longer than usual. The other four atoms form a square around the copper atom. The complex forms a one-dimensional polymer chain through the isothiocyanate ion. © 1990.
