Abstract
Chromocene reacts with aliphatic alcohols (n = 1 to 4) at 20 °C to give cyclopentadiene and very reactive chromium(II) alcoholates. All the prepared alcoholates are antiferromagnetic compounds with the Weiss constant -280 to -170 K. The magnetic moment corresponds to contribution of four unpaired electrons and to d4 configuration of Cr(II) atom. An interpretation of the antiferromagnetism of the alcoholates is suggested.
