A novel polymeric Hg[(CN)2N2] central core four-coordinate complex: Synthesis, X-ray structure and 199Hg, 13C and 15N CP MAS NMR characterization of catena((μ2-1,4-diaminobutane-N,N′)dicyanomercury(II))

Mercury(II) cyanide reacts with 1,4-diaminobutane (bn) at a 1:1 ratio forming a polymeric complex [(bn)Hg(CN)2]∞ in which (bn) acts as a bridge between the Lewis acid Hg(CN)2 moieties.
