Abstract
Die Phosphaniminato-Komplexe [ReO3(NPR3)] mit R = Ph (1) und R = Et (2) werden aus Dirheniumheptoxid und den silylierten Phosphaniminen Me3SiNPR3 hergestellt und ebenso wie das bei der Synthese von 2 als Nebenprodukt gebildete rote Silanolat [ReO(OSiMe3)3(Me3SiNPEt3)] (3) kristallographisch charakterisiert. 1 und 2 sind monomere Moleküle, in denen die Phosphaniminato-Liganden NPR3– kurze ReN-Bindungen von 179,3 pm (1) bzw. 178,6 pm (2) realisieren bei großen ReNP-Bindungswinkeln von 162,0° (1) bzw. 160,6° (2). In dem Rhenium(V)-Komplex 3 besetzt der Oxoligand die apicale Position der tetragonal-pyramidalen Koordination des Rheniumatoms, während die O-Atome der OSiMe3–-Gruppen zusammen mit dem N-Atom des Phosphanimin-Moleküls die Basispositionen einnehmen.
Phosphoraneiminato Complexes of Rhenium(VII). Syntheses and Crystal Structures of [ReO3(NPR3)] (R = Ph, Et) and of [ReO(OSiMe3)3(Me3SiNPEt3)]
The phosphoraneiminato complexes [ReO3(NPR3)] with R = Ph (1) and R = Et (2) are made from dirhenium heptaoxide and the silylated phosphoraneimines Me3SiNPR3. The complexes 1 and 2 as well as the red silanolate [ReO(OSiMe3)3(Me3SiNPEt3)] (3), which is formed as a by-product in the synthesis of 2, are characterized crystallographically. 1 and 2 are monomeric molecules, in which the phosphoraneiminato ligands NPR3– realize short ReN bonds of 179.3 pm (1) and 178.6 pm (2), respectively, with large ReNP bond angles of 162.0° (1) and 160.6° (2), respectively. In the rhenium(V) complex 3 the oxoligand occupies the apical position of the tetragonal pyramidal coordination of the rhenium atom, while the oxygen atoms of the Me3SiO– groups take the basic positions along with the nitrogen atom of the phosphaneimine molecule.
