The preparation and structural characterization of a chromium(III) complex with a potentially helicating ligand; the X-ray crystal structure of trans-dichloro(2,2′:6′,2″:6″,2‴-quaterpyridine-N,N′,N″,N‴)chromium(III) chloride tetrahydrate
摘要:
The reaction of 2,2':6',2":6",2'"-quaterpyridine (qpy) with chromium compounds has been investigated. Treatment with [Cr(H2O)4Cl2]Cl.4H2O for short periods results in the formation of [H2qpy]Cl2, but prolonged reaction times allow the preparation of salts of trans-[Cr(qpy)Cl2]+. The crystal structure of the salt trans-[Cr(qpy)Cl2]Cl.2H2O is described.
