Coordination compounds of various nickel(II) carboxylates (valerate, benzoate, phthalate, maleate, fumarate) with salicyl hydrazide have been synthesized and studied by IR spectroscopy. The crystal structure of the complex of nickel(II) phthalate with salicyl hydrazide [NiL3]Pht (L is salicyl hydrazide, Pht2– is phthalic acid dianion) has been determined by X-ray diffraction. The structural units of
已经合成了各种镍 (II) 羧酸盐(戊酸盐、苯甲酸盐、邻苯二甲酸盐、马来酸盐、富马酸盐)与水杨酰肼的配位化合物,并通过红外光谱进行了研究。已通过 X 射线衍射确定了邻苯二甲酸镍 (II) 与水杨酰肼 [NiL3]Pht(L 为水杨酰肼,Pht2– 为邻苯二甲酸二阴离子)的配合物的晶体结构。晶体的结构单元是复合阳离子[NiL3]2+ 和邻苯二甲酸阴离子Pht2- 通过阳离子-阴离子N-H…O、O-H…O 氢键连接在一起。镍原子具有由三个二齿螯合配体 L(Ni-O 2.027-2.059,Ni-N 2.067-2.097 Å)的三个氧和三个氮原子形成的扭曲八面体配位。
