A New Azelato Barium(II) Coordination Polymer Containing Chains of Water Molecules

The synthesis and characterization of α,ω-dicarboxylatecomplexes have attracted considerable attention during thepastdecade,duenotonlytotheirfascinatingstructures[1],butalso to their potential practical applications in a wide numberof fields [2].So far, extensive work has been carried out for carboxylatecomplexes and most of the reported studies have focused oncoordination frameworks with transition metal salts.Thepresentworkisacontinuationofearlierstudiesofalkaline-earthmetals(,(-dicarboxylatescomplexes[3].Toourknowledge,thenumberofstructuralstudiesofazelatecompoundsremainslimited[4]andnostructuralcharacterizationofalkaline-earthazelate have been reported.
