Hydrothermal synthesis and extended structure of poly[aqua(μ5-ethylenediaminetetraacetato)dizinc(II)].
In the extended structure of the title compound, [Zn(2)(C(10)H(12)N(2)O(8))(H(2)O)], prepared under hydrothermal conditions, there are two distinct Zn(II) sites. The first, with octahedral geometry, bonds to two N and three O atoms from one ethylenediaminetetraacetate tetraanion (EDTA) and one water molecule. The second, with tetrahedral geometry, coordinates to O atoms from four different EDTA ligands. The EDTA ligand almost encapsulates the octahedral Zn(II) ion and binds to four symmetry-related tetrahedral Zn(II) ions, hence generating the extended structure. One noncoordinated O-atom site on the EDTA ligand connects to the water molecule by hydrogen bonding. Structural comparisons are made with other compounds containing zinc, EDTA and water.
