Description
Summary:In this study, the molecular and crystal structures of iodocymantrenes [Mn(C<sub>5</sub>I<i><sub>n</sub></i>H<sub>5−<i>n</i></sub>)(CO)<sub>2</sub>(PPh<sub>3</sub>)] (<b>1b</b> <i>n</i> = 1; <b>2</b>, <i>n</i> = 2; <b>3</b>, <i>n</i> = 3) are reported and compared with the known structures of [Mn(C<sub>5</sub>I<i><sub>n</sub></i>H<sub>5−<i>n</i></sub>)(CO)<sub>3</sub>] (<b>1a</b>, <i>n</i> = 1; <b>5</b>, <i>n</i> = 5) and [Mn(C<sub>5</sub>I<sub>4</sub>H)(CO)<sub>2</sub>(PPh<sub>3</sub>)] (<b>4</b>). In the crystals, many weak interactions like H bonds (H…O, H…I, H…π), halogen bonds (I…I, I…O, I…C, I…π), and π-π contacts are found. Hirshfeld analyses show that H bonding is far more important when the PPh<sub>3</sub> ligand is present, and this is mainly based on dispersive interactions. However, without the PPh<sub>3</sub> ligand, H…I and other I…X contacts are the most frequently observed intermolecular interactions.
