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] · 3H2O} n (phen = 1,10-phenanthroline)

Abstract

Abstract A copper(II) polymeric complex {[Cu(phen)2(CN)][Ag(CN)2] · 3H2O} n , 1 (phen = 1,10-phenanthroline), has been prepared and structurally characterized. The compound crystallizes in the monoclinic space group P21/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.
