Schiff碱N,N’-二(2,5-二羟基水杨醛基)乙二胺与Co(Ⅱ)配合物的合成及晶体的培养

Synthesis of N,N′-dis(2,5-dihydroxysalicylidene)ethylenediaminato from Schiff Base with Cobalt(Ⅱ) and Cultivation of Crystal

水杨醛类Schiff碱N,N’-二(2,5-二羟基水杨醛基)乙二胺和六水合氯化钴在一定条件下可以形成配合物。文章重点介绍了在常温下配体与碱的摩尔比为1︰2、配体与金属盐的摩尔比为1︰2时,用分层法培养出N,N’-二(2,5-二羟基水杨醛基)乙二胺和六水合氯化钴所形成的黑色针状单晶。

The schiff base of N,N＇-dis（2,5-dihydroxysalicylidene）ethylenediaminato from salicylaldehyde and cobalt chloride hexahydrate could form coordination complexes under the certain condition. The black needle-shaped single crystals of coordination complex with N,N＇-dis（2,5-dihydroxysalicylidene）ethylenediaminato was introduced in the paper and cobalt chloride could be cultivated by layer method when ligand and metallic salts were mixed together according to 1 ： 2 of mole, and the mole ratio of ligand and alkali was 1 ： 2 under the room temperature.
