Abstract: The N-functionalized macrocyclic triamines derivatives have diverse applications in bioinorganic chemistry field.However,for the ten-member 1,4,7-triazacyclodecane (TACD),its N-Functionalized derivatives are less frequently reported because of their difficulty for synthesis.In this study,the complex of [NiL] [ClO4]2 based on N-functionalized ten-member TACD derivatives 1,4,7-tris (2-hydroxypropyl)-triazacyclodecane was synthesized and characterized by physico-chemical and spectroscopic methods.The crystal structure of [NiCl] · [ClO4]2 was determined by X-ray,which indicated the complex belongs to crystallographic system of monoclinic and space group:P2 (1)/n.The complex is hexacoordinate that six coordinating atoms come from three nitrogen atoms and three oxygen atoms of the ligand,and the center Ni atom exists in a distortion three prism coordination environment.A regular supramolecular network structure are formed through the hydrogen bonding N-H…O among the N atoms of the ligand and O atoms from perchlorate anion.
