Synthesis, structural analysis and antibacterial effect of a novel hetero-nuclear Ag(I)-Fe(II)
coordination polymer

he synthesis and crystal structure of a novel polymeric silver(I)-iron(II) complex containing bridging ligand
4’-(4-(2,2,2-tris(1H-pyrazol-1-ido)ethoxymethyl)phenyl-2,2’:6’,2”-terpyridine (TPT) are described. The reaction of TPT
with FeCl

which in turn reacted with a range of silver salts such as AgNO

resulted in the formation of hetero-metal complexes which were characterized using 1H NMR and ES-MS techniques. The
reaction solution of the [Fe(TPT)

complex with molar equivalent of AgClO

resulted in a solution with face needle-
like crystals suitable for single X-ray crystallography. The complex was crystallized the triclinic space group, Pī. The smallest

unit. The Fe atom is coordinated by three nitrogen of
terpyridine moiety from one TPT ligand and by three nitrogen of terpyridine moiety from another TPT ligand in an octahedral
geometry fashion. While one Ag atom is coordinated by two nitrogen atoms of one pyrazolyl moiety from a TPT ligand and
two nitrogen atoms of adjacent pyrazolyl moiety from another TPT ligand to generate a linear coordination polymer in a
tetragedral geometry. The third nitrogen atom of the last pyrazolyl part is also coordinated to a silver ion which was itself
coordinated to two water molecules through their oxygen atoms in a trigonal planar geometry. The shortest Ag-Ag distance is
5.337(1) Å within a TPT ligand. The Fe-Ag distances are 10.480(1) Å, 15.0637(1) Å within a unit cell.
In vitro
the study of the
complex against some bacterial pathogens were also investigated.
