Arene ruthenium complexes of N,N′- and N,O-donor schiff base ligands: an X-ray structure of [(η6-p-cymene) RuCl(C5,H4N-2-CHNC6H4-p-Me)Cl·C6H6·H2O
摘要:
Arene ruthenium(II) Schiff base complexes of formulations [(eta(6)-p-cymene)Ru Cl(C5H4N-2-CH = NC6H4-p-X)](ClO4) (1) and [(eta(6)-p-cymene)RuCl(O-omicron-C6H4CH = NC6 H4-p-X)] (2) (X = H, Me, OMe, NO2, Cl) were prepared by reacting [(eta(6)-p-cymene) RuCl2]2 with corresponding pyridine-2-carboxaldimines and sodium salts of salicylaldimines in dry THF, respectively. Complex 1 is isolated as a perchlorate salt. The molecular structure of [(eta(6)-p-cymene)RuCl(C5H4N-2-CH = NC6H4-p-Me)]Cl.C6H6.H2O has been determined by X-ray crystallography. The complex contains an eta(6)-p-cymene group, a chloride and a bidentate chelating Schiff base ligand.
