Two new lanthanide-pyridinetricarboxylic complexes formulated as [Lu(pyta)(H2O)3](1) and [La(pyta)· (H2O)2]·1.5H2O(2) were synthesized through hydrothermal reactions of LuCl3 or La(NO3)3·6H2O with pyridine-2,4,6-tricarboxylic acid(H3pyta), respectively, and characterized by X-ray crystallography. Complex 1 crystallized in the monoclinic system with space group P21/n, a=1.01930(12) nm, b=0.73423(9) nm, c=1.45449(17) nm, β=94.734(2)°, V=1.0848(2) nm3, Z=4. Complex 2 crystallized in the monoclinic system with space group P21/c, a=0.68474(8) nm, b=1.20982(15) nm, c=1.36063(17) nm, β=99.823(2)°, V=1.1106(2) nm3, Z=4. The overall structure of complex 1 consists of 2D binuclear Lu2(pyta)4-based grid coordination layers which are further extended into a 3D supramolecular architecture via hydrogen bonding interactions. With different coordination modes of the pyta ligand, complex 2 is a 3D porous network comprised of La-carboxylate framework.
