Abstract

[Li{C-5(CN)(5)}(H2O)] was prepared by salt metathesis between LiCl and [Ag{C-5(CN)(5)}], followed by recrystallization from methanol. The compound crystallizes in the orthorhombic space group Pnma and forms a coordination polymer. Three cyano substituents in 1,2,3 position coordinate to three different lithium ions forming a ribbon structure with adjacent 14-membered rings, while the remaining two cyano groups act as hydrogen bond acceptors towards two water hydrogen atoms of a neighboring ribbon. As a consequence, a wavy sheet structure results.
