Novel polymeric coordination complex [Ni(timpt)(2)](ClO4)(2) 1 was synthesized by solvothermal reaction of 2,4,6-tris[4-(imidazol-1-ylmethyl)phenyl]-1,3,5-triazine (timpt) ligand with Ni(ClO4)(2) (.) 6H(2)O and characterized by X-ray crystallography. Each Ni(II) is coordinated by six imidazolyl N atoms from six different timpt ligands with an octahedral geometry and each timpt ligand connects three metal atoms to generate a three-dimensional (3D) metal-organic framework with self-penetration. The uncoordinated perchlorate anions are located within the voids of the 3D structure through C-H-... O hydrogen bonds, which enable the complex to show anion-exchange property.
