Solvothermal Synthesis, Temperature-Dependent Structural Study, and Magnetic Characterization of a Multipolydentate Oxamate-Based 2D Coordination Network

Abstract

A multipolydentate N-substituted oxamate ligand bearing an additional carboxylato group has been successfully reacted in solvothermal conditions to form the 2D coordination network (TMA) 3 [CuMn(paba) 2 (OAc)]•8H 2 O (1). This coordination network displays a brick-wall type morphology with, thanks to the augmented connectivity of the ligand, a lower than usual metal ion nuclearity for the building subunit. Temperaturedependent structural studies indicate that the layered structure undergoes dehydration at 90 °C and remains stable up to 200 °C. Magnetic characterizations show that 1 behaves as a ferrimagnet, with a Curie temperature of 2.8 K.

“…The design and construction of coordination polymers (CPs) have received continuous attention over the past three decades due to their intriguing functionalities (Batten et al, 2008). These materials are assembled through the coordination bonds between metal ions and organic linkers, whereby their topologies and dimensionalities are highly dependent on synthetic parameters as well as the chemical nature of starting materials (Jiajaroen et al, 2022;Li et al, 2022). Among many others, CPs of group 12 metal ions have attracted great interest for their potential applications in photoluminescence and optoelectronics (Ren et al, 2014;Shang et al, 2020).…”
