Bis[1-methoxy-2,2,2-tris-(pyrazol-1-yl-κN 2 )ethane]-copper(II) bis-perchlorate (2) was synthesized by reacting of pyrazole based tripodal scorpionate ligand 1-methoxy-2,2,2-tris(pyrazol-1-yl)ethane (1) with copper(II) perchlorate hexahydrate in methanol, acetonitrile and water mixture as solvent. Slow evaporation of the filtered reaction mixture in air produced blue color block crystals suitable for single crystal X-ray diffraction study of the title complex. Compound 2 crystallizes in the monoclinic space group P2 1 /n with unit cell parameters, a = 8.1269(1) Ả, b = 21.8348(2)Ả, c = 9.1522(1) Å, α = γ = 90º, β = 99.7611(4)º. The structure of the compound was characterized by IR Spectroscopy, elemental analysis and single crystal X-ray diffraction analysis.
