Abstract

Three pairs of novel, isostructural polymeric iodometallate compounds, [H1,10-phen](H2O)1.41[AgI2] (1) ([H1,10-phen]+ = [1,10-phenanthrolinium]+), [H1,10-phen](H2O)1.42[CuI2] (2), [Co(tpy)2][Bi2I8] (3) (tpy = 2,2′:6′2″-terpyridine), [Fe(tpy)2][Bi2I8] (4), [Co(1,10-phen)3][Pb3I8]·H2O (5) (1,10-phen = 1,10-phenanthroline), and [Fe(1,10-phen)3][Pb3I8]·0.5(H2O) (6) have been synthesized solvothermally and characterized by single crystal X-ray diffraction. Compounds 1 and 2 are isostructural and crystallize in the orthorhombic space group Cmma with lattice parameters of a = 6.7063(7) Å, b = 17.6051(18) Å, c = 12.7088(13) Å and a = 6.5770(3) Å, b = 17.5245(8) Å, c = 12.5515(6) Å, respectively. The polymeric anionic chains in 1 and 2 are formed by edge-sharing MI4 (M = Ag, Cu) tetrahedra. Compounds 3 and 4 are isostructural and crystallize in the monoclinic space group P21/n with lattice parameters of a = 16.5085(7) Å, b = 16.0392(7) Å, c = 16.5115(7) Å, β = 97.4710(10)° and a = 16.4478(6) Å, b = 16.0645(6) Å, c = 16.4498(6) Å, β = 97.4490(10)°, respectively. Both structures contain the first observed, face-sharing [Bi2I8]2−anion cluster that is linked via corner sharing into infinite zig-zag anionic chains. Compounds 5 and 6 are isostructural and crystallize in the triclinic space group P1¯ with lattice parameters of a = 11.8798(5) Å, b = 15.2805(7) Å, c = 16.1889(7) Å, α = 63.9240(10)°, β = 74.0420(10)°, γ = 73.2540(10)° and a = 11.7889(5) Å, b = 15.3224(6) Å, c = 16.2584(6) Å, α = 64.1920(10)°, β = 73.5600(10)°, and γ = 73.7120(10)°, respectively. Compounds 5 and 6contain infinite [Pb3I8]2− chains in which the three crystallographically unique Pb2+ ions are found in sets of three trans face-sharing octahedra. These face-sharing trimers are observed in pairs that share three edges, and the pairs are further connected into 1-D chains by edge sharing with neighboring 2 × 3 units.
