Synthesis and Structure of Bis(Ethylenediamine-N,N-Di-3-Propionato)Zinc Dihydrate

Resumo

Bis(ethylenediamine-N,N-di-3-propionato)zinc dihydrate [Zn(EDDP)]₂ ∙ 2H₂O is prepared from dichloro(ethylenediamine-N,N-di-3-propionato)zinc in the presence of silver(I) oxide. The prepared complex is studied by X-ray diffraction and spectroscopic methods. A molecule of the complex has a centrosymmetric dimeric structure. Zn atoms have trigonal-bipyramidal coordination formed by the nitrogen atoms of primary and tertiary amino groups, two oxygen atoms of propionic groups of one EDDP molecule, and one oxygen atom of the other.
