Abstract

A silver(I)-saccharinato (sac) complex with nicotinamide (nia), [Ag(sac)(nia)] (n) has been synthesized and characterized by elemental analysis, IR spectroscopy, DTA-TG analyses and single crystal X-ray diffractometry. The complex crystallizes in monoclinic space group P2(1)/n with unit cell parameters of a=7.0258(4) angstrom, b=24.3784(10) angstrom, c=8.4301(5) angstrom, beta=109.407(5)angstrom, V=1361.85(13) angstrom(3) and Z=4. [Ag(sac)(nia)] (n) contains [Ag(sac)(nia)] units, which are doubly bridged by both nia and sac ligands, leading to a linear one-dimensional polymeric chains running along the a axis. The silver(I) ion has a highly distorted AgN2O2 tetrahedral geometry and the coordination polymer exhibits relatively short intra-chain ligand supported Ag center dot center dot center dot Ag separations of 3.1593(4) angstrom. The one-dimensional chains are crosslinked by N-H center dot center dot center dot O hydrogen bonds and aromatic pi(sac)center dot center dot center dot pi(nia) stacking interactions to generate a two-dimensional layer structure. IR spectra and thermal analysis data are in agreement with the crystal structure.
