Structure of a coordination polymer based on the bioctahedral [Re12CS14(SO2)3(CN)6]6– cluster anion and ammine complexes of Ni2+
2016
The first coordination polymer containing the [Re12CS14(SO2)3(CN)6]6– cluster anion is obtained and structurally characterized. The [{Ni(NH3)4}3{Re12CS14(μ-SO2)3(CN)6}]∙14H2O compound (1) is obtained by the reaction of NiCl2∙6H2O and K6[Re12CS14(μ-SO2)3(CN)6] in a mixture of NH3/H2O and CH3CN. The compound crystallizes in the triclinic space group P-1 with the unit cell parameters: a = 13.1633(4) A, b = 14.0464(4) A, c = 20.7198(7) A, α = 73.660(1)°, β = 83.101(1)°, γ = 65.102(1)°, V = 3334.6(2) A3, Z = 2, d calc = 3.661 g/cm3. The crystal structure is composed of linear polymeric chains located parallel to the b axis and solvate H2O molecules bound by hydrogen bonds.
