A new coordination compound, [(CuI)(Btd)]n(1, Btd=2,1,3-benzothiadiazole), was obtained at room temperature by the reaction of 2,1,3-benzothiadiazole with CuI and KI saturated aqueous solution. It was characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction analysis and photoluminescence. The complex crystallizes in the triclinic Pī space group, with a=4.1620(6), b=10.4590(15), c=10.5052(15), α=69.310(2), β=83.608(2), γ=78.873(2)o, V=419.30(10)3 , Z=2, C6H4N2SCuI, Mr=326.61, Dc=2.587 g/cm3 , F(000)=304 and μ(MoKα)=6.464 mm-1 . The final R=0.0418 and wR=0.0936 for 1451 observed reflections with I>2σ(I) and R=0.0422 and wR=0.0939 for all data. In the complex, the Cu atoms are coordinated by one nitrogen atom and three iodine atoms to form a double-stranded stair, and such stairs are further linked to build a 2D framework via C-H…I interactions.
