| Popis: | The six-coordinate complex [Re(mps)Cl2(PPh3)] (1) (H3mps = N-(2-amino-3-methylphenyl) salicylideneimine) was prepared by the reaction of [NH4][ReO4] with H3mps in the presence of triphenylphosphine and hydrochloric acid in glacial acetic acid. Crystallization from acetonitrile gave the product 1.CH3CN. The compound was characterized by spectroscopy and X-ray crystallography. The results show that the tridentate mps ligand coordinates via the doubly deprotonated 2-amino nitrogen (which is present in 1 as an imide), the neutral imino nitrogen and the phenolate oxygen. The imide and phenolate oxygen are trans to each other in a distorted octahedral geometry around the rhenium(V) centre, with the two chlorides in cis positions. |
