Abstract

AbstractStructural Chemistry, Thermo Analysis, Vibration Spectrum of PbBr2 · 2 C2D6O2 and Solubility of PbBr2 in short Chain Polyethylene GlycolesTemperature dependent solubility data of PbBr2 in short chain polyethylene glycoles completed with X‐ray diffraction data of the deposit are discussed. Crystals of PbBr2 · 2 C2D6O2 (1,2‐Ethandiole, furthermore called ethylene glycole) have been synthesized and structurally characterized by single crystal X‐ray investigations and powder‐neutron diffraction. PbBr2 · 2 C2D6O2 crystallizes in the monoclinic space group C2/c (No. 15) with a = 10.0887(2) Å, b = 10.8580(2) Å, c = 9.0997(1) Å, β = 92.382(2)° and Z = 4 (powder‐neutron diffraction data, 193 K). The compound can be described as a rod packing. The rods are built of nearly planar [PbBr4/2] units, surrounded by one ethylene glycol perpendicular to each side of the planar units. The linkage of these rods is realized by hydrogen bonds. A detailed description of hydrogen bonding in this compound is given.
