Structure and Bonding of the Manganese(II) Phosphide Complex (<i>t</i>-BuPH<sub>2</sub>)(η<sup>5</sup>-Cp)Mn{μ-(<i>t</i>-BuPH)}<sub>2</sub>Mn(Cp)(<i>t</i>-BuPH<sub>2</sub>)
No full textRather than achieving bis-deprotonation of the phosphine,
reaction
of Cp<sub>2</sub>Mn (Cp = cyclopentadienyl) with <i>t</i>-BuPH<sub>2</sub> at room temperature yields monodeprotonation of
half of the available phosphine in the product (<i>t</i>-BuPH<sub>2</sub>)Â(η<sup>5</sup>-Cp)ÂMnÂ{μ-(<i>t</i>-BuPH)}<sub>2</sub>MnÂ(Cp)Â(<i>t</i>-BuPH<sub>2</sub>) (<b>1</b>). This complex comprises a MnÂ(II) phosphide and is a dimer
in the solid state, containing a Mn<sub>2</sub>P<sub>2</sub> diamond
core. Consistent with the observation of a relatively short intermetal
distance of 2.8717(4) Ã… in <b>1</b>, DFT analysis of the
full structure points to a singlet ground state stabilized by a direct
Mn–Mn single bond. This is in line with the diamagnetic character
of <b>1</b> and an 18-electron count at Mn
