Structure Studies on Order Assemblage of Manganese II Isovanillin Complexes

Article Preview

Abstract:

The ManganeseII Isovanillin complex [Mn2(C8H7O3)4(H2O)2], Diaqua-tetra (isovanillinato-O,O')-bis (manganeseII),the MnII atom is coordinated by three isovanillinate anions and one water molecule in a distorted trigonal bipyramidal configuration with five-coordinations geometry. And one isovanillinate ligand chelates to the MnII atom through its methyl and hydroxy O atoms, the other two isovanillinate ligand chelates to the MnII atom only through its hydroxy O atoms. The same as another MnII atom. So we get a Binuclear MnII metal complexe. The fact clearly suggests not so much significant contribution from the electrostatic interaction in the Mn-O bonding in Binuclear MnII metal complexes as we gotten in mononuclear MnII metal complexes. Adjacent complex link to each other via hydrogen bonds forming the three-dimensional supramolecular structure.
