Abstract
The supramolecular coordination polymer (SCP) [Cu(CN)(2)(Me3Pb)phen]; 1 is formed by self-assembly of K-3[Cu(CN)(4)], Me3PbCl and 1,10-phenanthroline (phen) ligand at ambient conditions. The copper center is coordinated to two ordered cyanide ligands and two nitrogen atoms of the phen ligand forming distorted tetrahedral configuration. The structure of 1 consists of repeating units of the tetrahedral Cu(phen)(CN)(2) fragments connected by the (Me3Pb)(+) cations forming1-D helical chains. The 1-D helical chains are arranged in a unique way to construct a right-helical and a left-helical chain creating a double-helical 3-D network arranged in a unique A center dot center dot center dot A center dot center dot center dot A fashion. H-bonds and pi-pi stacking play an important role in stabilizing the structure of 1. IR, H-1-NMR, electronic and luminescence spectra as well as thermal analysis are also investigated. The SCP 1 has high antimicrobial activity against E. coli and S. aureus and it also exhibits good activity against the fungal strains, C. albicans and A. Niger. The results of growth inhibiting effect indicated that the inhibitory effect is increased with an increase in concentration of the SCP 1.
