Synthesis, Spectra, Thermal Analysis and Crystal Structure of a Mononuclear Oxalato-Copper(II) Complex with Monoethanolamine Cu(Mea) 2(Ox)

Abstract

cis-bis(Monoethanolamine)oxalatocopper(II), cis-[Cu(mea)<inf>2</inf>(ox)], has been prepared and characterized by elemental analyses, IR, UV-Vis, thermal analysis and single crystal X-ray diffraction. The title complex crystallizes in the triclinic form with Pi space group. The copper(II) ion lies on a center of symmetry and is octahedrally coordinated by two bidentate neutral mea (N,O) and one bidentate ox (O,O′) ligands. The individual molecules are held together by an extensive three-dimensional network of O-H⋯O, N-H⋯O and C-H⋯O type intermolecular hydrogen bonds. The IR spectrum and thermal decomposition of the title complex are described.
