TRIEN , triethylene tetramine

Abbreviations en = ethylene diamine dien = diethylene triamine trien = triethylene tetramine. 

The surfactant-cobalt(III) complex, dx-[Co(trien)(4CNP)(DA)](C10 )j (trien= triethylene tetramine, 4CNP = 4-cyanopyridine, and DA = dodecylamine), was synthesized (Fig. 4.13) and characterized by various spectroscopic and physicochemical techniques. The complex was tested in vitro on human hepatocellnlar liver carcinoma tumor cell lines and found to be active [84]. 

Ethylenediamine (en), diethylenetriamine (dien), triethylene-tetramine (trien), and tetraethylenepentamine (tetren) form well characterized complexes with M(ii) ions. Such complexes have been the subjects of a number of NMR exchange studies. (299-303) studies have established the identities of [Cu(en)(H20)4], [Cu(en)2-(HjOjj], and complexes involving both en and sulphosalicylic acid ligands. (299-301) NMR studies have been made on aqueous solutions of [Ni(dien)(H20)3], [Ni(tren)(H20)2], and...
