ORGANOMETALLIC COMPOUNDS AND POLYMERS BASED ON METAL-NITROGEN BOND SYSTEMS
Abstract
From the reaction of primary alkyl amines, with tris(diisopropylamino)-chromium (III) the tris-(alkylamino)chromium (III) compounds, Cr(NHR)3, were obtained as pink or red, insoluble, non-volatile solids which were significantly resistant to hydrolysis. Magnetic susceptibility measurements revealed anomalously low magnetic moments indicative of magnetically concentrated chromium atoms. It is suggested that these compounds are metalnitrogen co-ordination polymers with octahedrallyco-ordinated chromium. With branched chain primary amines entirely different products were obtained due to steric factors. Reactions between tetrakis-(dimethylamino) titanium, -zirconium, or -hafnium with nickel, iron, molybdenum or tungsten carbonyls gave interesting polymeric heterometalcarbonyldimethylamides. Reactions of aniline with tetrakis-(diethylamino)-titanium or tetrakis- (diethylamino)-zirconium gave soluble polymeric compounds.
