“…As in the Case of the bis(ethylene glycol) metal(II) halides (Antti, 1973(Antti, , 1975 and tris(ethylene glycol) metal(II) sulfates (Antti, 1972(Antti, , 1976a the ethylene glycol molecules in the ZnG12SO4 complex form chelates with the zinc ion. There are differences between the bis complexes of metal halides and sulfates: in metal chloride complexes (Antti, 1973(Antti, , 1975) the ethylene glycol molecules are arranged in an approximately square plane of the octahedron around the metal ion, while in both the tris (Antti, 1976b) and the bis complexes of metal sulfates one glycol molecule is placed in the equatorial positions and the others are bonded in the equatorial and apical positions of the octahedron.…”

“…In spite of the preparation and investigation of bis(1,2-ethanediol) metal(II) halides and sulfates (Knetsch and Groeneveld, 1973a,b) the crystal structure have been reported only for the bis complex of metal(II) halides (Antti, 1973(Antti, , 1975. As a part of our research work dealing with coordination chemistry of sugar-type compounds (Labadi et al, 1986(Labadi et al, , 1987) the bis(1,2-ethanediol) complex of zinc sulfate was prepared and its thermal stability and crystal determined.…”

Single crystals of the complex bis(1,2-enthanediol)zinc sulfate have been prepared. The crystal structure was determined by X-ray crystallography. Both 1,2-ethanediol (ethylene glycol) molecules chelate the zinc ion, the four glycolic oxygen atoms and the two oxygen atoms of the sulfate ion forming an octahedron around the zinc. Each sulfate ion is bonded to two zincs, forming an endless polymer chain. A hydrogen-bonding network between the ethylene glycol molecules and the sulfate ions is observed. On heating, the complex melts and decomposes, a polymeric structure of the thermal intermediate product is suggested.

“…uncharged) EG ligands were described more than a century ago by Grün , . In the 1970s, Antti published the crystal structures of some complexes obtained from 3d‐metal chlorides or sulfates and EG. Chloride (and other halide) ions are strong ligands, which typically reside in the first coordination sphere of metal cations.…”

Polyalcohols (polyols), such as ethylene glycol, have mild reducing ability. They are used in the so‐called polyol process to produce metallic nanoparticles of various kinds. In these syntheses, the effective reduction potential of the polyol strongly depends on the presence of other anions. Those anions compete against the polyol molecules for the direct bonding to the metal cations. As an indicator for the coordination behavior of polyols, we crystallized and structurally characterized 19 new coordination compounds with Mn, Co, Ni, Cu, Zn, Cd, Pb, or Bi. 15 of these compounds comprise nitrate ions, the others acetate ions. Compared to the already known chloride and sulfate analogues, nitrate shows an intermediate coordination affinity towards the metal cations considered here. While no direct metal–nitrate coordination occurs with Co2+, Ni2+, and Zn2+, mixed nitrate–polyol coordination environments are found for Mn2+, Cu2+, Cd2+, and Bi3+. Because of its strong chelating property, the acetate ion always coordinates the metal cation, competing with the polyol. The first mononuclear and dinuclear metal acetate diol coordination compounds were obtained with Co2+ and Cu2+, respectively. The coordination affinity of nitrate and acetate ligands in solid metal polyol complexes fully corresponds with our recent observations of the anion‐dependent reduction behavior of copper(II) salts in polyols.
