Synthesis, crystal structure and magnetic properties of a novel complex containing diamagnetic metal ion and radicals [Zn(NIT2-thz) 2(H 2O) 2]·(ClO 4) 2

Abstract

A novel complex [Zn(NIT2-thz) 2(H 2O) 2]·(ClO 4) 2 has been synthesized and structurally characterized by X-ray diffraction methods. It crystallizes in the triclinic crystal system and space group P I ̄ . The structure consists of [Zn(NIT2-thz) 2(H 2O) 2] 2+ moiety and two perchlorate anions. The Zinc(II) ion is in a distorted octahedral environment: one nitrogen atom and one oxygen atom from the NIT2-thz, one nitrogen atom and one oxygen atom from another NIT2-thz in the basal plane; two oxygen atoms from the two water molecules in the axial position. The units of [Zn(NIT2-thz) 2(H 2O) 2] 2+ were connected as one-dimension chain by the intermolecular hydrogen bonds. The complex exhibits intramolecular antiferromagnetic interactions between the NIT2-thz and the NIT2-thz.
