The complexes of [Cu(L)ClO4]ClO4 (1) and [Ni(L)](ClO4)2 (2) (L=1,4-bis(3-aminopropyl) piperazine) have been prepared from the reaction of Cu(ClO4)2•6H2O or NiCl2•6H2O with 1,4-bis(3-aminopropyl) piperazine, respectively, and have been determined crystal structure of them. The structure of 1 consists of [Cu(L)ClO4]+ cations and ClO4- counter anions.
and perchlorate counter anions. The copper(II) ion of 1 is coordinated four nitrogen atoms of the tetraaza ligand, and an oxygen atom of perchlorate group in a square-pyramidal arrangement and the nickel(II) ion of 2 is four coordinated with four nitrogen atoms of 1,4-bis(3-aminopropyl) piperazine ligand, in a square-planar arrangement. In this presentation, preparation and X-ray structure of 1 and 2 are discussed along with the afforded network structures in crystalline solids.
