Abstract

A three-dimensional heterometallic coordination polymer and a preparation method thereof relate to the coordination chemistry field. The invention adopts imidazole-4, 5-dicarboxylic acid and acetic acid as coordinators and adopts samarium ions and manganese ions as atoms to prepare the coordination polymer, (SmMn2(HIMDC)(CH3COO)(H2O))n, by changing the molar ratio of each substance and with a hydrothermal (solvothermal) synthesis technology. The novel coordination polymer has distinct structure and is a valuable luminescent material.

Description

technical field [0001] The invention relates to the field of coordination chemistry, in particular to a three-dimensional heterometallic coordination polymer [SmMn 2 (HIMDC)(CH 3 COO)(H 2 O)] n and its preparation method. Background technique [0002] Coordination polymers have various fascinating topological structures such as: one-dimensional chain and ladder structures, two-dimensional lattice, brick wall, honeycomb structures, and three-dimensional porous and diamond structures. More importantly, coordination polymers have important applications in zeolite-like molecular sieves, catalysis, nonlinear optics, magnetic materials and sensors. Coordination polymers include transition metal coordination polymers, rare earth metal coordination polymers, and heterometallic coordination polymers containing both transition and rare earth metals. Certain zinc coordination polymers have large three-dimensional pores, which can adsorb hydrogen, methane, and ammonia well. Many r...
