Synthesis and crystal structure of bis(dicyclohexylammonium) Tetracyanonickel(II)

Abstract

A novel, one-dimensional nickel(II) complex, [(C₆H₁₁)₂NH₂]₂[Ni(CN)₄], has been synthesized and structurally characterized by X-ray single crystallographic methods. The complex crystallizes in the triclinic, space group P1 with a = 9.237(1), b = 9.576(2), c = 9.689(3) Å, α = 61.51(2), β = 85.69(3), γ = 74.27(2)°, V = 723.6(3) ų, Z = 1. The square-planar Ni(II) centre of the cyanonickellate anion is four coordinated by cyanide ligands. The dicyclohexylammonium cation occupies a bridging position by hydrogen bonding to the cyanide ligand nitrogen atoms of adjacent anions.
