Synthesis and characterization of cyclotetrakis(μ-oxo-dimethylaminoethanolato-κN: κO)tetrakis(iodozinc) toluene solvate and Bis(dimethylaminoethanol)cadmium(II)iodide

Two new metal(II) complexes formulated as [ZnI(dmae)]₄·2(C₇H₈) 1 and CdI₂(Hdmae)₂ 2 have been synthesized by using N,N-dimethylaminoethanol, a N,O donor ligand and characterized by melting point, elemental analysis, FT-IR spectroscopy, mass spectrometry and single crystal X-ray diffraction analysis. Complex 1 crystallizes in tetragonal I4(1)/a space group with μ₂-O bridge between zinc atoms. The zinc atom is four coordinated with Zn-O 1.9315(13) and 1.9606(14) Å. The complex 2 is mononuclear with distorted octahedral geometry around the Cd(II) and contains two bidentate chelating Hdmae ligands and two iodine atoms, with Cd-O and Cd-N distances of 2.498(2) and 2.400(2) Å, respectively, and the weak O-H⋯I hydrogen bonds like interactions link the molecules to generate a 1D supramolecular structure.
