Abstract

A rhenium cluster complex [Ni(NH3)6]2.5⋅NH4[Re12CS17(CN)6]⋅8.5H2O is obtained and structurally described. The compound crystallizes in the triclinic space group P-1 with the unit cell parameters: a = 11.0856(13) Å, b = 15.242(2) Å, c = 21.232(3) Å, α = 90.158(4)°, β = 97.439(4)°, γ = 90.051(4)°, V = 3557.3(8) Å3, Z = 2, dcalc = 3.287 g/cm3. The crystal structure represents a packing of [Ni(NH3)6]2+ and NH4+ cations, [Re12CS17(CN)6]6– cluster anions, and crystallization water molecules bound by a system of hydrogen bonds.
