Abstract

Reaction of K₄[Fe(CN)₆] with Ni(CH₃COO)₂ and cyclen produced an unusual one-dimensional paramagnetic complex, [Ni(cyclen)]₂[Fe(CN)₆]·8H₂O (cyclen = 1,4,7,10-tetraazacyclododecane), that consists of [Ni(cyclen)]₂ dimers bridged by μ₃-cyanides from [Fe(CN)₆]^4-. The Ni⋯Ni distance is 3.303 Å, which is significantly shorter than the corresponding distance of 3.449 Å in [Ni₂(μ-N₃)₂(232-tet)₂] (PF₆)₂. Moderate antiferro-magnetic coupling occurs between the Ni²⁺ ions.
