Tetrakis[μ-3-(3-pyridyl)acrylato-κ2O:O′]bis{(1,10-phenanthroline-κ2N,N′)[3-(3-pyridyl)acrylato-κ2O,O′]europium(III)} pentahydrate

Abstract

The europiumIII ion in the title compound, [Eu2(C8H6NO2)6(C12H8N2)2]·5H2O, is coordinated by seven carboxylate O atoms and two N atoms from one phenanthroline molecule. The carboxylate groups of 3-(3-pyridyl)acrylate link pairs of europium(III) ions, forming centrosymmetric dinuclear units, which further assemble into a sheet parallel to the (001) plane through hydrogen-bonding interactions involving the uncoordinated water molecules. One water molecule is disordered.
