摘要
合成了双核锌(II)与1,4,8,11-四(水杨基氨基乙基)-1,4,8,11-四氮杂环十四烷(h4 tsaec)配合物[zn2 (tsaec)]·2CHCl 3。在293 K下用单晶x射线衍射法测定了晶体结构。配合物在单斜空间群p1 /c中结晶，a = 9.496(3)， b = 11.568(3)， c = 23.338(7)Å， β = 96.270(4)°，V = 2548.3(12)Å 3, D calcd = 1.505 g/cm 3, Z = 2。所有6119个独立反射的R 1 [I > 2 σ (I)]和wR 2(所有数据)值分别为0.0407和0.1034。两个锌(II)原子与中心三氮杂环十四烷环外的tsaec配体结合，分子内Zn··Zn距离为9.426(2)Å，其中每个锌(II)原子由两个希夫碱垂臂与两个酚氧和两个亚胺氮原子配位，形成扭曲的四面体几何形状。
Dinuclear Zinc(II) Complex with a Cyclam-based Ligand with Four Schiff-base Pendant Arms
Dinuclear zinc(II) complex with 1,4,8,11-tetrakis(salicylideneaminoethyl)-1,4,8,11-tetraazacyclotetradecane (H 4 tsaec), [Zn 2 (tsaec)]·2CHCl 3 , was synthesized. The crystal structure was determined by the single-crystal X-ray diffraction method at 293 K. The complex crystallizes in the monoclinic space group P 2 1 / c with a = 9.496(3), b = 11.568(3), c = 23.338(7)Å, β = 96.270(4) ° , V = 2548.3(12)Å 3 , D calcd = 1.505 g/cm 3 , Z = 2. The R 1 [ I > 2 σ ( I )] and wR 2 (all data) values are 0.0407 and 0.1034, respectively, for all 6119 independent reflections. The two zinc(II) atoms are bound to the tsaec ligand outside the central teraazacyclotetradecane ring with an intramolecular Zn···Zn distance of 9.426(2)Å, where each zinc(II) atom is coordinated by two Schiff-base pendant arms with two phenolato-oxygen and two imino-nitrogen atoms to form a distorted tetrahedral geometry.
