“…Coordination polymers have been studied for a long time in terms of architecture, topology, and their potential applications in catalysis [1][2][3], gas adsorption [4][5][6], chemical adsorption [7], luminescence [8,9], and design of molecular magnetic materials [10][11][12]. The proper choice of relevant ligands and metal centre is the key to form fascinating and useful coordination polymers [13][14][15][16][17][18][19][20][21][22][23].…”

Two previously synthesized cobalt(II) coordination polymers; {[Co(μ2-suc)(nia)2(H2O)2]·2H2O}n (suc = succinate(2−), nia = nicotinamide) and [Co(μ2-fum)(nia)2(H2O)2]n (fum = fumarate(2−)) were prepared and thoroughly characterized. Both complexes form 1D coordination chains by bonding of Co(nia)2(H2O)2 units through succinate or fumarate ligands while these chains are further linked through hydrogen bonds to 3D supramolecular networks. The intermolecular interactions of both complexes are quantified using Hirshfeld surface analysis and their infrared spectra, electronic spectra and static magnetic properties are confronted with DFT and state-of-the-art ab-initio calculations. Dynamic magnetic measurements show that both complexes exhibit single-ion magnet behaviour induced by a magnetic field. Since they possess very similar chemical structure, differing only in the rigidity of the bridge between the magnetic centres, this chemical feature is put into context with changes in their magnetic relaxation.

When the structures of the complexes of the same primary ligand with different metals and different co-ligands are evaluated in detail, it is thought that it will be easier to reach the target molecules by determining the factors affecting the structure. The study of the structures of metal(II) 2-fluorobenzoates with various N-donor ligands is aimed to contribute to future research. In this study, the crystal structures of transition metal(II) 2-fluorobenzoates with N-donor ligand complexes such as 2,2′-bipyridine, 1,10′-phenanthroline, nicotinamide, isonicotinamide, 4-pyridylmethanol, and 2-aminopyridine were investigated. According to the literature review, it was determined that Cu(II), Zn(II), Cd(II), Pb(II), Co(II), and Ni(II) 2-fluorobenzoates with N-donor ligand exhibit monomeric, dimeric, ionic, and polymeric structures. Although the fluorobenzoate anion has the most electronegative element (fluorine) at the 2-position in the benzene ring, only a few of its complexes have O–H⋯F, N–H⋯F, and C–H⋯F hydrogen bonds. A Pb(II) 2-fluorobenzoate complex without an N- donor ligand is the only complex in which the fluorobenzoate anion coordinates to the metal via the fluorine atom. The structures of the 19 complexes studied included 11 monomers, 5 dimers, 2 ionic, and 1 coordination polymer. In addition, 8 of these complexes are copper(II), 5 of them are Pb(II), 2 of them are Cd(II) and Zn(II), and one of them is Co(II) and Ni(II) metal centered. Many transition metal(II) 2-fluorobenzoate complexes can still be contributed to the literature, according to the findings of this study. Furthermore, because metal carboxylate complexes have various physical and biological potential applications today, their importance in materials science should be emphasized.
