A new 3D copper(II) coordination polymer, {[Cu2(tbip)2(1,3,5-tib)]2H2O}n (1, H2tbip = 5-tert-butyl isophthalic acid, 1,3,5-tib = 1,3,5-tris(1-imidazolyl)benzene), has been synthe- sized by hydrothermal reaction of Cu(OAc)2•4H2O, H2tbip and 1,3,5-tib. It has been structurally characterized by element analysis, IR and magnetic measurement. X-ray single-crystal analysis was carried out for 1, which crystallizes in the triclinic system, space group P with a = 7.822(3), b = 15.854(6), c = 17.553(6) Å, = 113.033(4), β = 90.694(4), = 101.006(4)°, V = 1957.3(12) Å3, Z = 1, Dc = 1.493 g/cm3, Mr = 1759.70, F(000) = 908, R = 0.0721 and wR = 0.1978 with I > 2(I). The single-crystal X-ray diffraction studies reveal that compound 1 exhibits 2D [Cu(tbip)] layers which are further pillared by 1,3,5-tib ancillary ligand with terminal tridentate coordination mode to generate the final 3D structure. Magnetic susceptibility data for 1 have been measured in the range of 2～300 K. There are antiferromagnetic interactions between copper ions of the compound.
