Ma, B., Gao, S., Jin, T, Wang, Z., Yi, T, Liao, C. et al. (1999) One-dimensional coordination polymer [Tm2(ttha)(H20)6Tm2(ttha)(H20)4]-21H20 n synthesis, crystal structure, thermal behavior and magnetism (Hettha = triethylenetetraminehexaacetic acid). Journal of Chemical Research, Synopses, 464-465, 1938-1951. 

Recently new data have become available on the stabilities of metal chelates formed from NTA and EDTA analogs, represented by XVIII, through the publication of equilibrium data on the chelates of two higher members of the series, triethylenetetraminehexaacetic acid (TTHA) and tetraethylenepentamineheptaacetic acid (TPHA) (5, 4)- The stabilities of some representative metal chelates of the series of ligands represented by Formula XVIII are listed in Table VI. 

BD = a-benzildioxime BO = a-benzoinooxime BP = 2,2 -bipyridine CA = chloranilic acid DHN=2,3-dihydroxynaphthalene DMG =dimethylglyoxime DMTD = 2,5-dimercapto-1,3,4-thiadiazole DTPA = diethylenetriaminepentaacetic acid FD=a-futildioxime HNB = A/-hydroxy-A/-nitroso benzeneamine MA = mandelic acid NO = nioxime NN = 1-Nitroso-2-naphthol PAN = 1-(2 -Pyridylazo)-2-naphthol PC = pyrocatechol TTHA=triethylenetetraminehexaacetic acid.
