Abstract
The new bimetallic supramolecular coordination polymers (SCP); (3) (a)[Cu(CN)(2)center dot Me3Sn center dot qaz], 1 and (3) (a)[Cu-2(CN)(4)center dot(Ph3Sn)(2)center dot qaz], 2 (qaz = quinazoline), are prepared in water/acetonitrile solvent at room temperature. The structure of 1 consists of the anionic Cu(CN)(2) building blocks connected by the Me3Sn cations to form zigzag chains which are bridged by qaz creating 2D-sheets. The interwoven infinite sheets are arranged in parallel A center dot center dot center dot A center dot center dot center dot A fashion developing 3D-network structure via H-bonds, pi-pi stacking, and Cu-C contacts. The network structure of 2 exhibits two different copper sites forming two Cu(CN)(2) building blocks which are connected by the Ph3Sn groups constructing elongated corrugated chains. The qaz ligand connects these chains forming 3D-network structure containing the rhombic [Cu-2(mu(3)-CN)(2)] motif. 1 and 2 are luminescent materials which can be used in applications as molecular sensing systems. Also, the catalytic activity of 1 and 2 was investigated towards the degradation of Metanil Yellow (MY) dye by dilute solution of hydrogen peroxide as oxidant.
