Abstract

Recrystallization of [Co(3,5-dbbq) ₂(L)] (3,5- dbbq = 3,5-di-tert-butyl-1,2-benzoquinone; L = bis(3-pyridyl)- phenylvinylsilane) from diethyl ether at -20 °C produces trans-[Co(3,5-dbbq) ₂(L) ₂] while the recrystallization from toluene at -20 °C gives trans-[Co(3,5-dbbq) ₂(L) ₂].2PhMe. The complex exists as trans-[Co ^III(3,5-dbsq)(3,5-dbcat)(L) ₂] (3,5-dbsq = 3,5-di-tert-butyl-1,2-semiquinonato; 3,5-dbcat = 3, 5-di-tert-butylcatecholato) in the solid state at 173 K. Differences in charge distribution between trans-[Co(3,5-dbbq) ₂(L) ₂] and trans-[Co(3,5-dbbq)2(L)2] 2PhMe have been observed based on the effective magnetic moments and IR spectra of the complexes along with their X-ray crystal structures.
