Synthesis and crystal structure of a 3D copper(II)-silver(I) coordination polymer assembled through hydrogen bonding, pi-pi stacking and metal-pi interactions, {[Cu(phen)(2)(CN)][Ag(CN)(2)] center dot 3H(2)O}(n) (phen=1,10-phenanthroline)

摘要

A copper(II) polymeric complex {[Cu(phen)(2)(CN)] [Ag(CN)(2)] center dot 3H(2)O}(n), 1 (phen = 1,10-phenanthroline), has been prepared and structurally characterized. The compound crystallizes in the monoclinic space group P2(1)/c with [Cu(phen)(2)(CN)](+) and [Ag(CN)(2)]-units and three water molecules. The cationic and anionic units are linked to each other through M-pi and pi-pi interactions. The array is extended further by hydrogen bonding and pi-pi interactions to form a 3D network.
