Three novel Ln(III)-Cu(I) coordination polymers, namely [LnCu(Hbic)(3)(ox)(0,5)] [Ln = Sm (1), Dy (2), Hbic = benzimidazole-5-carboxylate, ox = oxalate] and [EuCu(Hbic)(2)(ox)H2O]center dot 2H(2)O (3) have been hydrothermally synthesized and stucturally characterized. Both complexes 1 and 2 display the same unusual 2D layer heterometallic coordination frameworks that are built up by dimeric [Ln(2)(Hbic)(6)] cores and oxalate ligands by sharing Cu(I) ions. Complex 3 represents 1D polymeric chain architecture constructed from Eu2Cu2 ring units and oxalate ligands. Furthermore, the luminescent property of complex 3 has also been investigated.
