Abstract

Reaction of nickel(II) acetate with tren [tren = tris(2-aminoethyl)amine] and K[Au(CN)₂] produced [Ni(tren)Au(CN)₂][Au(CN)₂] (1), which consists of cis-[Ni(tren)]²⁺ units linked by Au(CN)₂^- to form infinite zig-zag chains. The complex obeys the Curie-Weiss law throughout the temperature range 4-300 K, with a Curie constant of 1.10 cm³ K mol^-1 and a Weiss temperature, θ, of 0.62 K. The electrospray mass spectrum of 1 in H₂O-CH₃OH shows peaks that can be described by the general formulae {[Ni(tren)](n)[Au(CN)₂](2n-1)}⁺ (n = 1-4) and {[Ni(tren)](n)[Au(CN)₂](2n-2)}²⁺ (n = 2-9). Based on the crystal structure of the polymer, these ions are best described as composed of an oligomeric cation that may be associated with one or more Au(CN)₂/^- counter ions.
