Abstract

Synthesis and crystal structure of a 3D copper(II)-silver(I) coordination polymer assembled through hydrogen bonding, π-π stacking and metal-π interactions, {[Cu(phen) 2 (CN)][Ag(CN) 2 ] · 3H 2 O} n (phen = 1,10-phenanthroline)[Ag(CN) 2 ] · 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-π and π-π interactions. The array is extended further by hydrogen bonding and π-π interactions to form a 3D network.
