摘要：

Two new 2D lanthanide coordination polymers [La(aip)(Haip)(H2O)(2)]center dot H2O (1) and [Sm(aip)(Haip)(phen)] (2) (H(2)aip = 5-aminoisophthalic acid) have been synthesized by hydrothermal reactions and characterized by IR, elemental analysis and X-ray single-crystal analyses. Compound 1 consists of a novel 2D layer structure formed by Haip ligands cross-linking 1D La-aip chains of dimers via carboxylate groups and compound 2 is composed of a 2D infinite grid-like network based on two kinds of Sm dinuclear units that are interconnected by carboxylate ligands. Finally they are all packed into three-dimensional frameworks through complicated hydrogen bonding. In addition, the photoluminescent properties of compound 2 have also been studied with excitation and emission spectra. (c) 2007 Elsevier Masson SAS. All rights reserved.
