Embodiment 1

[0044] First add 1mmol of benzophenone-2,4'-dicarboxylic acid into 4ml of distilled water and stir to dissolve, then add 1.5mmol of cobalt chloride, 1mmol of 2,2'-dipyridine and 3mmol of KOH in sequence while continuing to stir, and finally add 10ml of distilled water, the above mixed solution was stirred at room temperature for 10min, then transferred to a 23ml sealed polytetrafluoroethylene-lined reaction kettle, heated to 175°C in an oven, kept for 72h, and then slowly lowered to room temperature at 10°C / h. After the kettle was opened, a purple transparent single crystal was obtained with a yield of 86% (based on benzophenone-2,4′-dicarboxylic acid).

[0045] The structure of the obtained purple transparent single crystal was characterized. The X-ray diffraction data of the single crystal was obtained on the BrukerSmart Apex CCO surface probe diffractometer with MoK α radiation Collected in ω-scan mode and corrected by Lp factor, absorption correction uses SADABS program....

Embodiment 2

[0057] First add 1.2mmol of benzophenone-2,4'-dicarboxylic acid into 4ml of distilled water and stir to dissolve, then add 1.2mmol of cobalt chloride, 0.9mmol of 2,2'-dipyridine and 3.5mmol of KOH in sequence while stirring continuously, Finally, 10ml of distilled water was added, and the above mixed solution was stirred at room temperature for 10min, then transferred to a 23ml sealed polytetrafluoroethylene-lined reaction kettle, heated to 175°C in an oven, kept for 72h, and then slowly lowered to room temperature at 10°C / h. After opening the kettle, a purple transparent tri-nuclear and quad-nuclear mixed cobalt cluster coordination polymer (C 10 h 8 N 2 ) 4 (C 15 h 8 o 5 ) 6 (OH) 2 co 7 ·(H 2 O) 2 Single crystal, 75% yield (based on benzophenone-2,4'-dicarboxylic acid).

Abstract

The invention belongs to the field of coordination polymers, and particularly relates to a three-core four-core mixed cobalt cluster coordination polymer as well as a preparation method and application thereof. A chemical formula of the three-core four-core mixed cobalt cluster coordination polymer is (C10H8N2)4(C15H8O5)6(OH)2Co7.(H2O)2, wherein C10H8N2 is 2,2-dipyridyl; C15H8O5 is benzophenone-2,4'-diformate. The three-core four-core mixed cobalt cluster coordination polymer has the advantages that the preparation is easy; the stability is high; the polymer is an antiferromagnetic three-corefour-core mixed cobalt cluster coordination polymer with good potential application prospects in the fields of adsorption separation, hydrogen and energy storage, molecular magnets, catalysis, sensingand / or molecular recognition, and the like. The problem that no three-core four-core mixed cobalt cluster coordination polymer exists in the prior art, and three-core four-core mixed cobalt cluster coordination polymer performance study cannot be performed is solved. The invention also provides the preparation method of the three-core four-core mixed cobalt cluster coordination polymer; the three-core four-core mixed cobalt cluster coordination polymer prepared by the method has small defects, high crystallization degree and high yield.

Description

technical field [0001] The invention belongs to the technical field of coordination polymers, and in particular relates to a tri-nuclear and quad-nuclear mixed cobalt cluster coordination polymer and its preparation method and application. Background technique [0002] In recent years, the synthesis and properties of multinuclear transition metal clusters have become one of the research hotspots in the field of coordination chemistry and organometallic chemistry, because such metal clusters have important functions in molecular and ion exchange, adsorption, selective catalysis, optics and Molecular-based magnetic materials and other fields have potential application value. At present, many multinuclear transition metal clusters reported at home and abroad are coordination polymers of trinuclear cobalt clusters or tetranuclear cobalt clusters, but there is no report on trinuclear quadrinuclear mixed cobalt cluster coordination polymers. Therefore, the synthesis of tri-nuclea...
