A Zinc(II)-Silver(I) Bimetallic Coordination Polymer Assembled Through Argentophilic and π-π Interactions, {[Zn(phen)_2(H_2O) {Ag(CN)_2}][Ag(CN)_2]·MeOH}_n (phen=1,10-Phenanthroline)

摘要

A cyanido-bridged Zn(II)-Ag(I) bimetallic coordination polymer, {[Zn(phen)_2(H_2O){Ag(CN)_2}] [Ag(CN)_2]·MeOH}_n (1), was prepared using ZnCl_2, 1,10-phenanthroline (phen) and K[Ag(CN)_2] and characterized by IR spectroscopy, thermal analysis and X-ray crystallography. The crystal structure of 1 consists of dinuclear [Zn(phen)_2(H_2O){Ag(CN)_2}]~+ cations, [Ag(CN)_2]~- anions and a methanol molecule. The non-coordinated [Ag(CN)_2]~- anions are linked to the [Zn(phen)_2(H_2O){Ag(CN)_2}]~+ complex cations through argentophilic interactions leading to the formation of chains. The chains are connected by hydrogen bonds and p-p interactions to give a 3D network.
