A Polymeric Nickel(II) Thiocyanate Complex of N-(2-Aminoethyl)-N-methyl-1,2-ethanediamine

The structure of [Ni(medien)(NCS)(μ-SCN)]_n [medien is N-(2-aminoethyl)-N-methylethane-1,2-diamine, C₅H₁₅N₃] is a polymeric chain with each pair of neighbouring nickel(II) ions linked by one SCN⁻ bridging ligand. The coordination polyhedron about the Ni^II atom is a distorted octahedron consisting of three N atoms of the medien ligand coordinating facially, one N atom of the non-bridging thio­cyanate ligand, and one N and one S atom of two bridging thiocyanate ligands. The five-membered chelate rings display envelope geometry.
