Abstract

The new bimetallic supramolecular coordination polymers SCP 3 ∞CuCN2·Me3Sn·qaz 1 and 3 ∞Cu2CN4·Ph3Sn2·qaz 2 qaz = quinazoline are prepared in water/acetonitrile solvent at room temperature The structure of 1 consists of the anionic CuCN2 building blocks connected by the Me3Sn cations to form zigzag chains which are bridged by qaz creating 2Dsheets The interwoven infinite sheets are arranged in parallel A···A···A fashion developing 3Dnetwork structure via Hbonds π–π stacking and Cu–C contacts The network structure of 2 exhibits two different copper sites forming two CuCN2 building blocks which are connected by the Ph3Sn groups constructing elongated corrugated chains The qaz ligand connects these chains forming 3Dnetwork structure containing the rhombic Cu2μ3CN2 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
