A Mini Review on Monodentate Coordination Behavior of Dicyanoargentate Anion towards 3d Transition-Metal Ion, Blocked by Different Blocking Ligands

Abstract

Synthesis of coordination compounds using dicyanoargentate, [Ag(CN)2] as inorganic ligand is an interesting topic in the research area of supramolecular chemistry. Again cyano bridged compound is especially significant due to their remarkable structural diversity. As cyanometalate anions has strong affinity towards transition metal ions and it has been widely used as building blocks for the creation of coordination polymer. Dicyanoargentate anion, [Ag(CN)2] can behaves as bridging ligandas well as monodentate ligand and discrete anion. This review article mostly highlights the monodentate coordination behavior of dicyanoargentate anion towards 3d-transition metal ion in which the transition metal ion is blocked by different blocking ligands. This review also reveals the formation of different dimensionality complexes through Ag···Ag interactions when dicyanoargentate anion act as monodentate ligand.
