Embodiment 1

[0027] 0.1mmol Co(NO 3 ) 2 ·6H 2 O was placed at the bottom of the test tube, dissolved with 5mL of distilled water to form reaction solution A; 15ml of methanol and water mixed solution C with a volume ratio of 1:1 was added in the middle; 0.1mmol H 2 L and 0.1 mmol 4,4′-bipy were dissolved in 5 mL of methanol, and 0.05 mL of 2,6-lutidine was added to obtain reaction solution B, which was placed on the upper layer of the test tube. After being sealed and left standing for 24 days, a wine red massive single crystal appeared at the junction of the solution interface on the test tube wall. The crystals were washed successively with distilled water, methanol and ether, and dried. The yield was about 50%.

Abstract

The invention relates to a 1-(4-carboxy phenyl)-5-sulfydryl-1H-tetrazole and 4, 4'-bipyridyl blending cobalt composition and a preparation method thereof. The composition has a chemical formula as follows: {[Co(L)(4, 4'-bipy)(H2O)2](H2O)2}, wherein L=1-(4-carboxy phenyl)-5-sulfydryl-1H-tetrazole anion ligand; and 4, 4'-bipy=4, 4'-bipyridyl. The composition is prepared by adopting a diffusion method which is different from synthesizing methods, i.e. a hydrothemal method and the like, of a conventional cobalt metal carboxylic ligand blending composition reported in the traditional literature and overcomes the technical defects of high temperature, pressure and danger, low productivity, difficult purification and separation and poor repeatability; the synthesizing method showed by the invention has moderate condition, high productivity and good repeatability at normal temperature and pressure; and in addition, a magnetism test result of a crystal sample of the composition lays the theoretical foundation for further developing a novel magnetic-function molecular material.

Description

technical field [0001] The invention belongs to the field of transition metal complex materials, in particular to a 1-(4-carboxyphenyl)-5-mercapto-1H-tetrazole and 4,4'-bipyridine mixed cobalt complex and a preparation method thereof. The complex has a two-dimensional network structure and can be further developed and applied as a magnetic material. Background technique [0002] In recent years, coordination polymers have attracted many domestic and foreign scholars to research in this field because of their diverse topological structures and excellent properties. Optical materials, adsorption, catalysis and many other aspects have shown excellent application prospects. So far, people have prepared a large number of coordination polymers and studied their properties. The ligands used are mostly carboxylic acids and nitrogen heterocycles. Cobalt metal complexes have been synthesized and studied a lot because of their diverse structures and potential properties, and they ha...
