摘要：
The complex salt trans-[Re(mps)Cl(PPh3)(2)](ReO4) (1) (H(3)mps = N-(2-amino-3-methylphenyl)-salicylideneimine) was prepared by reaction of trans-[ ReOCl3(PPh3)(2) with a twofold molar excess of H(3)mps. The compound was characterized by spectroscopy and X-ray crystallography. The results show that the trianionic ligand mps acts as a tridentate chelate via the doubly deprotonated amino nitrogen ( which is present in 1 as an imide), the neutral imino nitrogen and the deprotonated phenolic oxygen atoms. The imido nitrogen and phenolate oxygen atoms coordinate trans to each other in a distorted octahedral geometry around the rhenium(V) centre.
