摘要

A new one-dimensional [CuC_(16) H_(18) N_4O_4S]_n(1) was synthesized by the self-assembly of a ligand 2,5-thiophenediformates, 3,5-dimethylpyrazole and copper(II), and characterized by elemental analysis, IR and single-crystal X-ray diffraction. 1 crystallizes in monoclinic, space group C2/c with unit cell parameters, a=18.6156(4), b=5.96110(10), c=18.1598(4), A=115.467(2)°, Z=4, V=1819.37(7)A~3, Mr=425.94, Dc=1.555g/cm~3, μ=1.345 mm~(-1), and F(000)=876. The final R and wR are 0.0328 and 0.0816 for 7611 observed reflections with I>2σ(I). 1 shows an infinite 1-D polymeric chain structure based on the repeated basic units Cu(II)(3,5-dimethylpyrazole)2(2,5-thiophene diformate). The Cu(II)center acts as the joint of the unit, and is coordinated in a slightly distorted octahedral geometry comprised of four O atoms from two different 2,5-thiophenediformate ligands and two N atoms of two trans 3,5-dimethylpyrazole ligands.
