  One-dimensional zinc-based coordination polymers incorporating cyanate anions

  摘要：

  Two one-dimensional zinc-based coordination polymers containing cyanate anions are reported. catena-Poly[ sodium [[tricyanatozinc(II)]-mu-1,4-diazabicyclo[2.2.2] octane-kappa(2) N:N']], {Na[Zn(NCO)(3)(C6H12N2)]}(n), consists of linear [tricyanatozinc( II)]-mu-1,4-diazabicyclo[2.2.2] octane strands in which the Zn2+ cations adopt trigonal - bipyramidal coordination on sites of (6) over bar m2 point symmetry. Na+ cations lie between the strands on sites of (3) over barm point symmetry, coordinated in a distorted octahedral geometry by six O atoms of the cyanate anions. catena-Poly[[dicyanatozinc(II)]-mu-4,4'-bipyridine-kappa N-2: N'], [Zn(NCO)(2)(C10H8N2)](n), crystallizes in the space group P2(1)/n with Z' = 5. The structure consists of zigzag strands formed by Zn2+ cations linked via 4,4'-bipyridine. Each Zn2+ cation adopts a tetrahedral coordination, with two sites occupied by 4,4'-bipyridine and two cyanate anions completing the coordination sphere. The structure is closely comparable with the thiocyanate and halide analogues [ZnX2(C10H8N2)] (X = NCS, Cl or Br).
