Source of material
5-Aminoisophthalic acid (AIPH2) (0.02 g, 0.1 mmol), 4,4′-dipyridylsulfide (dps; 0.02 g, 0.1 mmol) and nickel(II) acetate tetrahydrate (0.03 g, 0.1 mmol) were added to water (7 mL) in a Teflon-lined stainless steel reactor with a small amount of a base. The mixture was heated at 393 K for 3 d, and then slowly cooled down to room temperature. Green crystals of the title compound were obtained.
Experimental details
The hydrogen atoms were placed at calculated positions with the SHELX program (AFIX options: 43 and 147).
Comment
The rational design of metal–organic complexes has received remarkable attention and has developed rapidly due to their fascinating potential applications in functional materials, [4], [5], [6], [7], [8], [9], [10], [11]. All aspects of this research hotspot have been deeply discussed by some recent reviews, which show that the diverse structures of such materials are always dependent on many factors, such as substituent and number of coordination sites provided by organic ligands, ligand to metal salt ratio, template, metal ion, pH value, and counteranion [12]. In recent years, one of our interests focuses on the coordination assembly based on bis(pyridine) ligands and aromatic polycarboxylic acids ligands. In 4,4′-dipyridylsulfide ligand, two pyridine rings can keep different dihedral angles around the sulphur atom in the process of forming a complex. On the other hand, the aromatic polycarboxylic acids can form complexes with metal ions in flexible way, which can enhance stability of the complex [13]. As a continuation of our previous investigation, in this study we reacted 5-aminoisophthalic acid with Ni2+ ions, then employed 4,4′-dipyridylsulfide ligand as an auxiliary ligand, which features di-nuclear structure.
The asymmetric unit of title complex contains one independent Ni(II) cation, one AIP2− anion, two coordinated H2O and one dps ligand. Each Ni center is six coordinated by two carboxylato O atoms from one AIP2− ligand, two N atoms from one dps ligand and one AIP2− ligand and two water molecules to form a slight distorted octahedral geometry (see the figure). The two carboxylic O atoms of the AIP2− molecule are coordinated with Ni(II) by chelate mode. The Ni—O lengths are in the range of 2.029(4)–2.140(4) Å. The Ni—N lengths are 2.144(5)(Ni-N1A) and 2.080(6) (Ni-N2) Å. Two carboxylate groups of each AIP2− ligand have a dihedral angle of 23.49° and 26.17° toward the plane of the corresponding linking phenyl rings, respectively. The dps ligand shows obvious torsion with a dihedral angle between the two pyridine rings of 80.39°.
