Terminal ligand effect on the structure variation of Copper(II) complexes

Two copper(II)–poly(pyrazolyl)methane complexes [Cu2(bpm)4(ta)](ClO4) 2 · 2H2O 1 and {[Cu2(tpm)2(ta)2] · H2O}n2 (bpm = bis(3,5-dimethylpyrazolyl)methane, tpm = tris(pyrazolyl)methane, H2ta = terephthalic acid) were synthesized and characterized by elemental analysis, FT-IR and UV–vis spectra. 1 is a binuclear complex, while 2 exhibits as a 1D zigzag coordination polymer.
