A novel one-dimensional coordination polymer, catena-poly[μ-succinatobis(isonicotinamide-κN)diaquacobalt(II)], [Co(suc)(ina)2(H2O)2]n (suc = succinate, ina = isonicotinamide), was synthesized via the reaction of cobalt(II) chloride hexahydrate,
sodium hydroxide, succinic acid, and isonicotinamide in aqueous methanol.
Structural characterization using single-crystal X-ray diffraction, FTIR
spectroscopy, and thermal analysis revealed that Co(II) exhibits an octahedral
coordination geometry, with succinate bridging the cobalt centers to form a
one-dimensional polymeric chain. Extensive hydrogen bonding stabilizes the
three-dimensional supramolecular architecture.
Keywords: cobalt(II), polymer, isonicotinamide, succinic acid, XRD, crystal structure.
