摘要
Mercury(II) cyanide reacts with 1,4-diaminobutane (bn) at a 1:1 ratio forming a polymeric complex [(bn)Hg(CN)(2)](infinity) in which (bn) acts as a bridge between the Lewis acid Hg(CN)(2) moieties. The metal complex coordination sphere Hg[(CN)(2)N-2] is best described as distorted trigonal pyramidal. The C-13 and N-15 CP MAS NMR data show two chemically different CN groups consistent with the hydrogen bonding scheme involving only one of the cyano ligands. (C) 2009 Elsevier B.V.
