Four new lanthanide complexes, [Nd(4-Pyta)3(H2O)2]n (1), [Ce(4-Pyta)3(H2O)2]n (2), [Eu(4-Pyta)3(H2O)2]n (3) and [Gd(4-Pyta)3(H2O)2]n (4), have been obtained from reaction of lanthanide(III) nitrate with 4-Pyta (4-pyridylthioacetate) in water. Their structures were characterized by elemental analysis, infrared spectroscopy and single-crystal X-ray diffraction. The crystals belong to triclinic, space group P1 and all complexes exhibit one-dimensional chains that arrange to form a three-dimensional supramolecular architecture by hydrogen bonds between the chains.
