Abstract

The structure of the complex [Eu(m-MOBA)₃·2H₂O]l/2(4,4'-bpy) (m-MOBA: m-methoxybenzoate, 4,4'-bpy: 4,4'-bipyridine) was determined by single crystal X-ray diffraction. The bonding around each europium consists of two oxygen atoms of the chelated carboxyl group, two oxygen atoms of two water molecules and four oxygen atoms of the bidentate bridging carboxylate groups, forming an infinite polymeric chain structure. The luminescence behaviour of Eu³⁺ in {[Eu(m-MOBA)₃·2H₂O]l/2(4,4'-bpy)}∞ was observed at 77 K. The emission spectra of ⁵D₁ → ⁷F(J) (J = 1-3) and ⁵D₀ → ⁷F(J) (J = 0-4) transitions were recorded. The complex displays intense luminescence which may be related to the m-MOBA ligand and the polymeric coordination. (C) 2000 Elsevier Science B.V.
