A new compound containing discrete cationic and anionic complexes, [Cu(pyr)3](Hg2I6 (C30H24CuHg2I6N6), where pyr = 2,2'-bipyridine, was prepared by the reaction of CuBr with pyr and HgI2 in a mixed solvent of acetone, methanol and acetonitrile. Single-crystal X-ray diffraction analysis indicates that it crystallizes in an orthorhombic system, Pna21 (No. 33), a = 33.1595(7), b = 9.4605(1), c = 13.0899(2) A。, V = 4106.4(1) A。3, Mr = 1694.67, Dc = 2.741 g/cm3, Z = 4, F(000) = 3012, μ(MoKα) = 12.511 mm-1, R = 0.0736, wR = 0.1360 (I > 2σ(I)) and S = 1.218. The structure consists of discrete [Hg2I6]2- anions and [Cu(bipyridine)3]2+ cations. The double tetrahedral [Hg2I6]2- unit is formed by sharing one tetrahedral edge and possesses approximate D2h symmetry. The mononuclear Cu2+ ion is coordinated by six N atoms from three pyr molecules to form a slightly disordered octahedral geometry.
