Abstract
The first coordination polymer containing a [Re12CS14(SO2)3(CN)6]6- cluster anion is obtained and structurally characterized. The [{Ni(NH3)4}3´{Re12CS14(m-SO2)3(CN)6}]×14H2O compound (1) is obtained by the reaction of NiCl2×6H2O and K6[Re12CS14(m-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, a = 73.660(1)°, b = 83.101(1)°, g = 65.102(1)°, V = 3334.6(2) Å3, 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.
