Crystal structure and photoluminescent properties of a new EuIII-phthalate-acetate coordination polymer

A new coordination polymer, poly[(acetato)aqua(μ3-phthalato)europium(III)], [Eu(C8H4O4)(CH3O2)(H2O)] n or [EuIII(phth)(OAc)(H2O)] (phth2- = phthalate and OAc- = acetate) was synthesized and characterized, revealing it to be a supra-molecular assembly of one-dimensional [EuIII(phth)(OAc)(H2O)] chains...

Description
Summary:A new coordination polymer, poly[(acetato)aqua(μ3-phthalato)europium(III)], [Eu(C8H4O4)(CH3O2)(H2O)] n or [EuIII(phth)(OAc)(H2O)] (phth2- = phthalate and OAc- = acetate) was synthesized and characterized, revealing it to be a supra-molecular assembly of one-dimensional [EuIII(phth)(OAc)(H2O)] chains. Each chain is built up of edge-sharing distorted tricapped trigonal-prismatic TPRS-{EuIIIO9} building motifs and assembled in a regular fashion through hydrogen-bonding and aromatic π-π inter-actions. The fully deprotonated phth2- ligand was shown to be an effective sensitizer, promoting the characteristic 5 D 0→7 FJ (J = 1-4) emissions of EuIII even in the presence of the non-sensitizing OAc- group.A new coordination polymer, poly[(acetato)aqua(μ3-phthalato)europium(III)], [Eu(C8H4O4)(CH3O2)(H2O)] n or [EuIII(phth)(OAc)(H2O)] (phth2- = phthalate and OAc- = acetate) was synthesized and characterized, revealing it to be a supra-molecular assembly of one-dimensional [EuIII(phth)(OAc)(H2O)] chains.
