Embodiment 1

[0025] Example 1 Preparation of organometallic complex crystals of platinum

[0026] 1) Add 10g of 2,2'-bis(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole into 100ml of ethanol, then add glycine and stir to dissolve;

[0027] 2) Add acetic acid aqueous solution to the solution in step 1) to adjust the pH to 3.2, and then raise the temperature to 40-45°C;

[0028] 3) Add 1 mol / L aqueous solution of platinum acetylacetonate to the solution in step 2). After the addition, raise the temperature to 60-65°C and stir for more than 12 hours; calculated by molar ratio, 2,2'-bis(o-chlorophenyl) -4,4',5,5'-tetraphenyl-1,2'-biimidazole: glycine: acetylacetonate metal salt=4: 2.3:2.2;

[0029] 4) Cool down to room temperature, adjust the pH to 8.2 with sodium bicarbonate to obtain an alkaline solution;

[0030] 5) The alkaline solution was left to stand for more than 32 hours to form a large amount of solids, filtered, the filter cake was rinsed with n-heptane, and then dried und...

[0032] Example 2 Preparation of Zinc Organometallic Complex Crystals

[0033] 1) Add 10g of 2,2'-bis(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole into 100ml tetrahydrofuran, then add glycine and stir to dissolve;

[0034] 2) Add aqueous oxalic acid solution to the solution in step 1) to adjust the pH to 3.2, and then raise the temperature to 40-45°C;

[0035] 3) Add 1 mol / L aqueous solution of platinum acetylacetonate to the solution in step 2). After the addition, raise the temperature to 60-65°C and stir for more than 12 hours; calculated by molar ratio, 2,2'-bis(o-chlorophenyl) -4,4',5,5'-tetraphenyl-1,2'-biimidazole:glycine:acetylacetonate metal salt=4: 2.3:2.5;

[0036] 4) Cool down to room temperature, adjust the pH to 8.2 with sodium bicarbonate to obtain an alkaline solution;

[0037] 5) The alkaline solution was left to stand for more than 32 hours to form a large amount of solids, filtered, the filter cake was rinsed with n-heptane, and then dried under r...

Abstract

The invention belongs to the technical field of plant protection, and concretely relates to a preparation method and a use of organic metal complex crystals. The organic metal complex crystals are prepared from 2,2'-bis(ortho-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole, glycine and acetylacetone metal salt. The organic metal complex crystals have a crop disease control effect, and is especially used for controlling Botrytis cintrea, Colletotrichum nicotianae, cotton wilt fusarium, Physalospora piricola and Bipolaria maydis.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to a preparation method and application of an organometallic complex crystal. Background technique [0002] Crop diseases and insect pests are one of the main agricultural disasters in our country. It has the characteristics of various types, great impact, and frequent outbreaks. The scope and severity of its occurrence and severity often cause heavy losses to our national economy, especially agricultural production. Common crops in my country are the following types of pests and diseases: rice planthopper, powdery mildew, corn borer, cotton bollworm, wheat rust, cotton aphid, rice sheath blight, rice blast, wheat aphid, wheat red spider, locust, wheat gibberella It has become a major pest and disease that seriously affects my country's agricultural production. [0003] Tobacco anthracnose is caused by fungal infection of the genus Ignomonia subhexapia. After t...
