tetrazole

Metal and triazole/ tetrazole can be built mononuclear, binuclear and trinuclear complexes. Carboxylic acid ligands are introduced the M-triazole/ tetrazole system, leading to coordination polymers and supermolecular structures by different coordination modes and intermolecular interaction. 2.

金属与唑类配体可形成单核、双核、三核结构单元，羧酸类配体再通过不同的配位模式及分子间作用力将其连接成为配位聚合物及三维超分子结构。

The common method, such as protein electrophoresis, tetrazole staining burgeon experiment and farm experiment can measure vigour and purity of seed, but it can not be satisfied for actual request of seed producing in the way of speed and precision of data processing and result analyse.

蛋白电泳、四唑染色、发芽率实验和田间实验等常规方法虽能测定种子纯度和活力，但在数据处理的速度、精度和结果分析等方面远远不能满足种子生产的实际需要。

Replaced 2-chloropyridine in ABT-594 with 2-methyl-5-nitroimidazole or 5-methyl tetrazole, and ( or) instead of the CH_2O with CH_2 as linking arm, the analgesic activity didn ′ t obviously decrease.

用2-甲基-5-硝基咪唑或5-甲基四氮唑代替吡啶和2-氯吡啶，用亚甲基代替氧桥键作为连接臂所合成的化合物，其镇痛活性并无明显下降；
