Variable-temperature Mössbauer, magnetic susceptibility, and infrared studies of Fe(phen)2(NCBH3)2 reveal the occurrence of a reversible, gradual singlet/quintet intersystem crossing above room temperature. Mössbauer spectra of the complex in the transition region are interpreted as showing the occurrence of a novel (for Fe(II)), fast singlet/quintet interconversion.
