“…68%) in the decomposition curve in the temperature range of 220-450 °C comprises the removal of pyridine cations and oxalate groups as a strongly exothermic process [28]. This technique was used to check the number of water molecules as well as the nature of connections with the network of these molecules.…”

We report herein the synthesis and physicochemical characterization of a new mixed-ligand iron(III)This compound is prepared by slow evaporation at room temperature and characterized by single crystal X-ray diffraction. It is characterized by IR and UV-VIS spectra and thermal analysis (TG and DTA). In this compound, the iron ion has a slightly distorted square bipyramidal environment, coordinated by two chelating oxalate ions and two water molecules. Structural cohesion is essentially established by π-π interactions between the rings of pyridine groups and intermolecular hydrogen bonds connecting the ionic entities and uncoordinated water molecules. Magnetic susceptibility measurements exhibit the paramagnetic behavior at high temperatures. However, at low temperatures, the magnetic data show the occurrence of weak antiferromagnetic intermolecular interactions between the local spins.

“…While other complexes of lanthanide chlorides with 4,4′-bipyridine have been reported, they have not been structurally characterized. 19 It is notable that, despite all molecular components being apolar, half of the known Ln-aquo-bpy structures crystallize in polar space groups. The [M(H 2 O) 8 ]Cl 3 ‚(bpy) 2 complexes, for instance, both show a strong piezoelectric effect.…”

“…These complexes form a 3-D hydrogen-bonded lattice structure, which is topologically the same as the self-catenating nitrate complexes and is discussed in more detail below. While other complexes of lanthanide chlorides with 4,4‘-bipyridine have been reported, they have not been structurally characterized . It is notable that, despite all molecular components being apolar, half of the known Ln-aquo-bpy structures crystallize in polar space groups.…”

A series of three-dimensional (3-D) hydrogen-bonded structures of lanthanide aquo ions and 4,4′-bipyridine (bpy) or protonated bpyH + as ligands and hydrogen-bonding tectons have been characterized by single-crystal X-ray crystallography, with both Cland [Co(C 2 B 9 H 11 ) 2 ]counteranions. All show related structures with unidirectional rectangular channels filled by additional bpy molecules for the complexes [Yb(H 2 O) 8 ](bpy) 2.5 Cl 3 ‚6.5(H 2 O) and [Yb(H 2 O) 8 ] 4 (bpy) 9.5 Cl 12 ‚24.5(H 2 O) or by [Co(C 2 B 9 H 11 ) 2 ]anions for the complexes [Ln(bpy)(H 2 O) 8 ] 2 (bpy) 10 [Co(C 2 B 9 H 11 ) 2 ] 6 ‚1.5(EtOH)‚15(H 2 O) where Ln ) La, Ce, [Sm(H 2 O) 5 (bpy) 2 (EtOH)]-[Sm(H 2 O) 6 (bpyH)(EtOH)](bpyH)(bpy) 10 [Co(C 2 B 9 H 11 ) 2 ] 8 ‚EtOH‚9(H 2 O), and [Ln(H 2 O) 6 (bpy)(bpyH 0.5 )] 2 [Ln(H 2 O) 7 (bpy)](bpyH) 2 -(bpy) 14 [Co(C 2 B 9 H 11 ) 2 ] 12 ‚n(EtOH)‚5(H 2 O) where Ln ) Gd, Tb, and Ho. The smaller (CB 11 H 12 )anion does not template a similar structure; instead the complex [(bpyH) 3 (bpy)(CB 11 H 12 ) 3 ] is isolated with a one-dimensional (1-D) hydrogen-bonded ladder structure.
