Cobalt(II) complexes with aminopolycarboxylate 1,3-pdta-type ligands: synthesis and characterization of trans(O6)-[Mg(H2O)6][CoII(1,3-pddadp)]·H2O

Abstract

Starting from Ba 2 (1,3-pddadp) Á 8H 2 O (1,3-pddadp ¼ 1,3-propanediamine-N,N¢-diacetate-N,N¢-di-3-propionate ion) and CoSO 4 , a new hexadentate [Co II (1,3-pddadp)] 2) complex has been prepared. The trans(O 6 ) geometry of this complex was confirmed by comparison of its i.r. and u.v.-vis. spectra with those of [Co II (1,3-pdta)] 2) (1,3-pdta is the 1,3-propanediaminetetraacetate ion) and trans(O 6 )-[Co III (1,3-pddadp)] ) complexes of known X-ray crystal structure. Magnetic and electrolytic conductivity properties of these complexes have also been discussed.

Transformations of lead 1,3-propylenediaminetetraacetate to its MOF products for the selective adsorption of methanol

“…It has similar coordination ability with ethylenediaminetetraacetic acid. However, the 1,3-H 4 Mg [7], Co [8,9], Ni [10,11], Cu [10,12,13] and Zn [14] [15] and Cd [14,15] [17] and La-1,3-pdta with MOF structure [18,19] (4) have been prepared and full characterized. It is notable that 1 is well water-soluble which is similar to lead ethylenediaminetetraacetates, and could be converted to the insoluble products of 3 and 4.…”

The effects of pH values on the formations of water soluble calcium 1,3-propylenediaminetetraacetates

“…It has similar coordination ability with ethylenediaminetetraacetic acid. However, the 1,3-H4pdta can form a Mg [9] , Co [10,11], Ni [12], Cu [13,14] and Zn [15] [18] and La-1,3-pdta with MOF structures [19,20] have been isolated using 1,3-pdta ligand. Quantum mechanical charge field molecular dynamics is also used for the structural and dynamic study of calcium ethylenediaminetetraacetate in solution [21].…”
