Abstract:
Based on 2-(4-carboxyphenyl)imidazo[4,5- f ]-1,10-phenanthroline (HNCP) and 2,5-thiophenedicarboxylate (TDC 2− ) ligands, three new lanthanide-containing (Sm, Nd, and Pr) compounds, [Sm(NCP)(TDC)] n ( 1 ), [Nd(NCP)(TDC)] n ·2 n (H 2 O) 0.5 ( 2 ), and [Pr(NCP)(TDC)] n · n (H 2 O) 0.5 ( 3 ), have been synthesized using the hydrothermal method and structurally characterized using single-crystal X-ray diffraction. Structural analyses have revealed that compounds 1–3 are 3D isostructural metal-organic frameworks in which the [Ln 2 (COO) 4 ] dimers can be regarded as 6-connecting nodes, and the TDC 2− and NCP − ligands are simplified as connectors to achieve the double interspersed 3D networks with the point symbol {4 12 ·6 3 }. Thermogravimetric analysis has illustrated that the rigid architecture contributes to superior thermal stability with a thermal decomposition temperature of more than 400°C for the resulting metal-organic frameworks.
