Displacement of tetrahydrofuran ligands by tripodal phosphines. Crystal structure of [MoCl3{N(CH2CH2PPh2)3}]·C4H8O

Abstract

The complexes [MoCl₃{P(CH₂CH₂PPh₂)₃}]·thf and [MoCl₃{N(CH₂CH₂PPh₂)₃}]·thf (thf = tetrahydrofuran) have been prepared from [MoCl₃(thf)₃] by ligand replacement reaction of thf. An X-ray crystal structure investigation of [MoCl₃{N(CH₂CH₂PPh₂)₃}]·thf shows a distorted-octahedral structure with a meridional arrangement of the three chlorine ligands. The amine acts as tridentate ligand with a pendant PPh₂ group.
