摘要
One three-dimensional Gd(III) coordination polymer with 1,2-phenylenediacetate (PDA(2-)), [Gd-2(PDA)(3)(H2O)(2)].3H(2)O (1), has been successfully synthesized and characterized. Single-crystal X-ray diffraction analysis shows that 1 consists of 1D wave Gd-based chain unit and PDA(2-)linker. Magnetic studies suggest the presence of ferromagnetic Gd-Gd coupling in the 1D chain unit of 1. Meanwhile, 1 has a significant cryogenic magnetocaloric effect with the maximum -Delta S-m of 33.44 at 2K and 7T. (C) 2017 Elsevier B.V. All rights reserved.
