The new bimetallic supramolecular coordination polymers (SCP); 3 ∞ [Cu(CN) 2 ·Me 3 Sn·qaz], 1 and 3 ∞ [Cu 2 (CN) 4 ·(Ph 3 Sn) 2 ·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 Me 3 Sn cations to form zigzag chains which are bridged by qaz creating 2D-sheets. The interwoven infinite sheets are arranged in parallel A···A···A fashion developing 3D-network structure via H-bonds, π-π 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 Ph 3 Sn groups constructing elongated corrugated chains. The qaz ligand connects these chains forming 3D-network structure containing the rhombic [Cu 2 (μ 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.
