The binary and ternary stability constants of DL-α-Alaninc with Cu(Ⅱ),Zn(Ⅱ),Ni(Ⅱ) and Cd(Ⅱ) were determined by pH polcntiometric titration at 37±0.1℃ and ionic strength 150mM/dm3.Potentiomeinc data were treated with ZPLOT,MAGEC,MINIQUAD and ESTA programs.The compositions of complex species were ascertained in the complex equilibriums by selection of different chemical models.The lgK and lgX values indicate that the complexes with mixed li-gands were obviously more stable than the simple binary systems especially in the zinc-alaninate-histidinale-proton system.Distribution curves of the complex species show the continuity of stepwise cotnplexing in the formation of complexes.At physiological pH region these complexes,except cadium system,existed mainly in the form of neutral complexes which have biological significance in the transfer of metal ons acrossing the membrane.

In this work, rare earth nicotinate coordination compounds with 1, 10-phenanthroline have been synthesized. The composition of these coordination compounds was determined by chemical analysis, IR spectra and ~1H NMR spectra. Results show that the composition of these coordination compounds is corresponding to the formula of RE(phen)_2L_3·nH_2O(where RE=La, Ce, Pr, Nd, Sm, Eu, Gd, phen=1, 10-phenanthroline, L=anion of nicotinic acid, n=2~5). As determined via thermal analysis, IR spectrum and molar conductance data these compounds are characterized as neutral compounds with 8-coordinate structure. Based on the IR spectra data for △v=v_(as(coo~-)~(-V)s(coo~-), it is supposed that the bridging coordination mode of carboxylate ions to rare earth elements changes to the unidentate coordination mode in rare earth nicotinate coordination compounds with 1, 10-phenanthroline. As △v data increase with the increasing of atomic number of rare earths, the RE-O bonds will strengthen accordingly. As shown by thermal analysis, RE-N bonds in the coordination compounds also gradually strengthen with the increasing of atomic number of rare earths. X-ray diffraction analysis shows that gadolinium coordination compound belongs to triclinic crystal system with cell parameters: a=9.03, b=12.86, c=17.74, α=84.9°, β=8.0.5°, γ=84.7.

Hydrous Smcl_3, Eucl_3, Gdcl_3, Tbcl_3 reacts with sodium 3-methylbenzoate(NaMBA) in water respectively, to form 3-Methylbenzoic acid complexes of rare earths, again reacts with 1, 10-phenanthroline (phen) in 1,4-dioxane to form a class of new solid complexes of rare earths. They were inverstigated by elemental analysis, molar conductance, IR spectra, UV absorption spectra, differeiantl thermal analysis (DTA), thermagravimetry (TG) and X-ray photoelectron spectroscopy (XPS).The new complexes have the composition of [Ln(MBA)_3·phen] (Ln=Sm~(3+), Eu~(3+), Gd~(3+), Tb~(3+)). IR spectra and XPS indicate that Ln are coordinated by carboxy group of 3-methylbenzoic acid and nitrogen atoms of 1, 10-phenanthroline. The molar conductance data reveal that these complexes are characterized as neutral compounds with 8-coordinate structure. The TG and DTA results show that the decomposition temperature of complexes is about 540℃.
