Structure of a coordination polymer based on the bioctahedral [Re12CS14(SO2)3(CN)6]6– cluster anion and ammine complexes of Ni2+

Abstract

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) Å, b = 14.0464(4) Å, c = 20.7198(7) Å, α = 73.660(1)°, β = 83.101(1)°, γ = 65.102(1)°, V = 3334.6(2) ų, 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.
