摘要
A novel two dimensional heterometallic coordination polymer, Nd 2Zn 3(EDTA) 3(H 2O) 11 ·12H 2O (EDTA= ethylenediamine N,N,N',N' tetraacetate) was synthesized and characterized. In the compound, each Nd 3+ is connected to three Zn 2+ through three carboxylate bridges, while each Zn 2+ has two Nd 3+ neighbors. In this way, a macrocycle involving six neodyium and six zinc ions is produced. The cycles are connected each other to form a two dimensional sheet. These sheets are further linked into a three dimensional network by the water molecules between the layers through rich hydrogen bonding.
