Synthesis, Structure, and Property of One Nickel(II) Metal–Organic Frameworks Based on 4-Methylphthalic Acid and Imidazole-Containing Ligand

Abstract

The title compound, {[Ni(L)(bbi)(H₂O)₃]·(H₂O)} _n (I), where H₂L = 4-methylphthalic acid and bbi = 1,1′-(1,4-butanediyl) bis(imidazole), crystallizes in the triclinic form with space group Pī and exhibits a 1D metal-organic chain. The Ni^II cation is coordinated to four O atoms from one L^2– ligand and three coordinated water molecules, respectively, and two N atoms from two different bbi ligands, and these six donor atoms form an octahedral configuration. The bbi ligands connect the Ni^II cations to form infinite chains, with the L ligands hanging on the two sides, which are further linked by rich hydrogen bonding system to generate a 3D supramolecular structure.
