木虫 (小有名气)

[求助] 麻烦哪位高人给解释一下这个实验步骤是啥意思?谢谢~

The SCPs 1–3, were prepared by the same procedure under the same conditions. A solution of 85 mg (0.5 mmol) of AgNO3 in 10 mL H2O was being added at room temperature to the mixture of (0.5 mmol) of the bipodal ligand; L, in 10 mL MeCN and of 48 mg (0.5 mmol) of KSCN in 10 mL H2O.White turbidity appeared then after concentrated ammonia solution was added to the hot mixture dropwise with stirring till clearness. The mixture was filtered off and the filtrate was left to stand for some days. Prismatic colorless crystals of 1 appeared after two weeks. After filtration, subsequent washing with small portions of water and MeCN and overnight drying, about 109 mg of [(AgSCN)2 · bpy] 1 were obtained.  Also, brown prismatic crystals of [(AgSCN)2 ·(tbpe)], 2, were formed after two
weeks and filtered off then after washed with small portions of water and MeCN and dried overnight. Ninety-six milligrams of 2 were obtained. Brown needle crystals of 3 were formed after one week and filtered off then after washed with small portions of water and MeCN and dried overnight. Sixty-two milligrams of [(AgSCN)2·phenz], 3, were obtained.

知道的麻烦告诉下,尤其红字部分,还有那个bipodal ligand是什么意思,和后面的L有关系吗? 谢谢了。

【答案】应助回帖

1.在10 mL 水中加入85 毫克 (0.5 mmol)  AgNO3 ,配成溶液.
2.在10 mL 水中加入10 毫升 MeCN 和48 毫克(0.5 mmol) KSCN ,制成配合物溶液。
然后在室温下将步骤1的溶液加入到步骤2中制成的溶液,即可完成该实验步骤。
