“…Nevertheless, the photo‐physical behavior of the CuCN‐amine networks appears to be closely related to CuCN itself . Thus, the emission band at 400 nm of 1 and that at 420 nm of 2 resemble that of CuCN which is assumed to arise from transitions from the lowest excited‐triplet state to the ground state. Lifetime studies of soluble Cu(1)‐cyano species have suggested that emission is usually a phosphorescence phenomenon .…”

The new synthesized supramolecular complexes (SC); [Cu2(CN)4(Et3Sn)2(tbpe)], 1 and [Cu2(CN)3(Et3Sn)(bpe)], 2 (tbpe = trans‐1,2‐bis(4‐pyridyl)ethene and bpe = 1,2‐bis(4‐pyridyl)ethane), were characterized by elemental analyses, electrical conductance, spectroscopic studies and thermal analyses. UV–Vis spectra and magnetic moment data suggested the tetrahedral geometry around Cu(I) atoms. The structures of the SC 1 and 2 were also theoretically studied using molecular mechanics (MM+). The structures were minimized with a semi‐empirical (PM3) method. The organotin compounds represent significant advances in the clinical management of some cancer cell lines. 1 and 2 were tested as inhibitors and their citotoxicities showed potent growth inhibitory activity for hepatocellular carcinoma HePG‐2, mammary gland breast cancer MCF‐7, human prostate cancer PC3 and Colorectal carcinoma HCT‐116 cell lines. The tested compounds showed high inhibitory anti‐oxidant activity either using erythrocyte hemolysis or ABTS method.

“…The possible photophysical sources of luminescence behavior in 1 are the Laporte allowed excitation of a p-p ⁄ type [51] and single-metal-centered (MC) transitions or metal-to-ligand charge transfer (MLCT). The emission band at 430 nm resembles that of CuCN [52] which is assumed to arise from transitions from the lowest excited-triplet state to the ground state. Life time studies of soluble Cu(1)-cyano species have suggested that emission is usually a phosphorescence phenomenon [53,54].…”

“…On the other hand, the possible photophysical sources of luminescence behavior in 1 and 2, for the remaining two peaks at 390 and 475 nm, can be argued to the MC transition and MLCT, respectively. The emission band at 385 nm of 1 and that at 390 nm of 2 resembles that of CuCN [51] which is assumed to arise from transitions from the lowest excited-triplet state to the ground state. Lifetime studies of soluble Cu(1)-cyano species have suggested that emission is usually a phosphorescence phenomenon [52,53].…”

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.
