| Abstract: A new three-dimensional copper dithiocarbamate-copper iodide coordination polymer [Cu(Me2dtc)2(CuI)3]n(Me2dtc=N,N-dimethyldithiocarbamate) was synthesized by reactions of Cu(OAc)2, NaI and Na(Me2dtc) in DMF solution, characterized by elemental analysis, IR spectrum, and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group C2/c with a=1.293 89(17) nm, b=1.077 61(11) nm, c=1.456 05(17) nm, β=115.585(4)°, V=1.831 1(4) nm3, Z=4, Dc=3.175 g·cm-3, Mr=875.28, λ(Mo Kα)=0.071 073 nm, μ=10.082 mm-1, F(000)=1 604, the final R=0.029 5 and wR=0.081 7. A total of 2 083 unique reflections were collected, of which 1 918 with I>2σ(I) were observed. The Cu atoms are Cu(Ⅰ)/Cu(Ⅱ) mixed-valence and they have two different coordinate geometries, namely planar square and tetrahedron. This three-dimensional structure consists of individual Cu(Me2dtc)2 molecules linking together CuI polymeric chains which run parallel to the [001] direction vis Cu-S bonds. CCDC: 739046. |
