Syntheses, Structures and Characteristics of Two New Cu(II) Coordination Polymers Based on 4-tert-butyl-phthalate and Different Bis(1,2,4-triazol-1-yl) Co-Ligands

Two new Cu(II) coordination polymers, [Cu-2(tbph)(2)(btb)(2)](n) (1) and {[Cu-2(tbph)(2)(bth)(2)]center dot H2O}(n) (2), (H(2)tbph = 4-tert-butyl-phthalic acid, btb = 1,4-bis(1,2,4-triazol-1- yl)butane, bth = 1,6-bis(1,2,4-triazol-1-y)hexane), have been synthesized and characterized by elemental analysis, FT-IR and X-ray single-crystal diffraction. Complex 1 has a 2D sql layer. Complex 2 shows a (3,4)-connected 2D sheet with a (4.6(4).8)(4.8(2)) topology. The thermal behavior of the two corresponding complexes has briefly been investigated.
