Strukturchemie, thermoanalytische und schwingungsspektroskopische Untersuchungen von PbBr 2 · 2 C 2 D 6 O 2 und Löslichkeitsuntersuchungen von Bleibromid in kurzkettigen Polyethylenglykolen

Structural Chemistry, Thermo Analysis, Vibration Spectrum of PbBr 2 · 2 C 2 D 6 O 2 and Solubility of PbBr 2 in short Chain Polyethylene Glycoles Temperature dependent solubility data of PbBr 2 in short chain polyethylene glycoles completed with X‐ray diffraction data of the deposit are discussed. Crystals of PbBr 2 · 2 C 2 D 6 O 2 (1,2‐Ethandiole, furthermore called ethylene glycole) have been synthesized and structurally characterized by single crystal X‐ray investigations and powder‐neutron diffraction. PbBr 2 · 2 C 2 D 6 O 2 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   ∞ 1 [PbBr 4/2 ] 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.
