What Is The Structure Of Nickel Ii Cyanide?

Nickel(II) cyanide has the chemical formula Ni(CN)2. The structure of this compound can be described as a coordination complex, where a central nickel ion is surrounded by two cyanide (CN-) ligands. Each cyanide ligand binds to the nickel ion through a nitrogen atom in the CN group.

The geometry around the nickel ion is octahedral, meaning that the two CN ligands are arranged in a cis configuration with respect to each other. This results in a linear arrangement of the three atoms (nickel, carbon, and nitrogen) in each CN ligand.

Overall, the molecular structure of nickel(II) cyanide can be visualized as a central nickel ion at the center of an octahedron, with one CN ligand bound above and one below the plane defined by the four remaining coordination sites.
