摘要

The reaction of the potentially bidentate ambidentate N,O-donor ligands 3-hydroxy-2-pyridinecarboxylic acid (Hhpc) and 3-hydroxy-2-(hydroxymethyl)pyridine (Hhhp) with trans -[ReOCl~(3)(PPh~(3))~(2)] led to the isolation of the products [ReOCl(hpc)~(2)] ( 1 ) (from acetonitrile) and [ReOCl~(2)(hhp)(PPh~(3))] ( 2 ) (from ethanol) respectively. In both complexes hpc and hhp are coordinated as bidentate N,O-donor chelates, rather than as O,O-donor ligands. From the reaction of [Re(CO)~(5)Cl] and Hhhp·HCl in ethanol the neutral complex fac -[Re(CO)~(3)Cl(Hhhp)] ( 3 ) was obtained, with N,O-coordination of Hhhp. Complex 1 crystallizes in the monoclinic space group P 2~(1)/n with a ?=?6.8782(3), b ?=?20.0647(8), c ?=?10.8692(4)??, β ?=?107.545(1)°, and Z ?=?4. Complex 2 crystallizes in the triclinic space group P -1 with a ?=?7.3523(4), b ?=?8.1047(5), c ?=?19.591(1)??, α ?=?91.133(2)°, β ?=?93.656(2)°, γ ?=?93.074(2)° and Z ?=?2. Complex 3 has monoclinic P 2~(1)/c symmetry with the cell parameters a ?=?10.6452(5), b ?=?11.1372(5), c ?=?9.7229(5)??, β ?=?106.107(2)°, and Z ?=?4.
