Abstract:

One novel macrocyclic triamine derived ligand N,N',N″-tris(2-hydroxypropyl)-1,4,7-triazacyclodecane and its transition metal complexes, [CoL] [ClO4]2 were synthesized and characterized by physico-chemical and spectroscopic methods. The crystal structure of [CoL][ClO4]2 was determined. The complex belongs to crystallographic system of monoclinic and space group:P2/N(1). The complex is hexacoordinate and the center Co atom exists in a distortion three prism coordination environment. The six coordinating atoms come from three nitrogen atoms and three oxygen atoms of the ligand. The average Co—N bond length and Co—O bond length are 0.2114(6) nm and 0.2097(6) nm, respectively. A regular supramolecular network structure are formed through the hydrogen bonding O••••H—O between three oxygen atoms of the perchlorate with three oxygen atoms of the neighboring ligands.
