| Darstellung, Kristallstruktur und Infrarotspektrum von [MONC13 * P0C13]4 Preparation, Crystal Structure and Infrared Spectrum of [MONC13 * P0C13]4  | | | | Abstract
| [MoNCl3 • P0C13]4 is prepared both by the reaction of MoNCl3 with POCl3 as well as by the reaction of M0CI5 with NC13 in the presence of P0C13. [MONC13 • P0C13]4 crystallizes in the monoclinic space group P2i/c with 2 tetrameric molecules in the unit cell. The crystal structure was solved by X-ray diffraction methods (R — 0.033, 1821 observed reflections). The structure consists of planar and almost square Mo4N4-eight-membered rings with alternating Mo-N bond lengths. The distorted octahedral environment of the molybdenum atoms is completed by three terminal Cl-ligands and by the oxygen atom of a POCl3 molecule, which is coordinated trans to the Mo = N triple bond. The IR spectrum is discussed with respect to the vibrational spectra of the isoelectronic niobium complex [NbOCl3 • P0C13]4. | | | |
