Popis: The hydrothermal reactions of Nd(ClO4)3·6H2O, Gd(ClO4)3·6H2O, Dy(ClO4)3·6H2O, Er(ClO4)3·6H2O with 1,3-dicyanobenzene, give rise to four one-dimensional rare earth-based coordination polymers: [M(3-CNC6H4COO)3(H2O)2] n (where M = Nd (1), Gd (2), Dy (3), Er (4), 3-CNC6H4COO = 3-cyanobenzoato), respectively. Their solid-state structures have been characterized by X-ray single-crystal diffraction studies. The results show that 1,3-dicyanobenzene hydrolyzed to give 3-cyanobenzoato under hydrothermal condition, and the four complexes are isomorphous.
