“…Such SMMs have high luminescence and ferroelectric capabilities in some situations, paving the way for a new class of multifunctional materials that could be used in quantum computers, memory devices and multiferroics [29][30][31][32][33][34][35] . Coordination polymers of silver(I) and cadmium(II) with the polydentate N-donor ligand 4-(pyridin-2-yl)methyleneamino-1,2,4-triazole (L) were studied previously [36][37][38] . Moreover, lanthanide(III) (Eu, Gd, Tb, Dy) complexes derived from 4-(pyridin-2yl)methyleneamino-1,2,4-triazole were also prepared [39] .…”

Samarium-benzylidene Schiff base adduct with the formula [Sm(NO3)3(H2O)3].2L (L= (E)-1-phenyl-N-(4H-1,2,4-triazol-4-yl) methanimine) (1) has been prepared, with two water molecules bonded to the samarium center form hydrogen bond with three molecules of title Schiff base through nitrogen atoms of the triazole rings. The chemical structure was confirmed by means of single-crystal X-ray diffraction (scXRD), FT-IR, electrical conductivity, thermogravimetric analysis (TGA), mass spectrometry and elemental analysis. The title complex 1 crystallizes in the triclinic P-1 space group. The unit cell parameters are a = 10.4045(1) Å, b = 12.5403(1) Å, c = 12.5477(2) Å,  = 96.668(1)o,  = 110.810(1)o,  = 111.567(1)o, V = 1.788 Å3, Z = 2, Rgt(F) = 0.0223, wRref(F2) = 0.0576. The samarium ion is in a distorted capped square antiprism environment, coordinated by three bidentate nitrates and three coordination water molecules. The [Sm(H2O)3(NO3)3] complex and the (E)-1-phenyl-N-(4H-1,2,4-triazol-4-yl)methanimine) moiety (L) are held together via hydrogen interactions to form a 2-D supramolecular framework. It is a non-electrolyte as indicated by its molar conductivity (ΛM= 10.1 S cm2 mol-1) in MeOH at 1.0 mM. The mass spectral results confirm the suggested structure of the investigated adduct.

The reaction of lanthanide(III) nitrates with 4-(pyridin-2-yl)methyleneamino-1,2,4-triazole (L) was studied. The compounds [Ln(NO ) (H O) ]⋅2 L, in which Ln=Eu (1), Gd (2), Tb (3), or Dy (4), obtained in a mixture of MeCN/EtOH have the same structure, as shown by XRD. In the crystals of these compounds, the mononuclear complex units [Ln(NO ) (H O) ] are linked to L molecules through intermolecular hydrogen-bonding interactions to form a 2D polymeric supramolecular architecture. An investigation into the optical characteristics of the Eu -, Tb -, and Dy -containing compounds (1, 3, and 4) showed that these complexes displayed metal-centered luminescence. According to magnetic measurements, compound 4 exhibits single-ion magnet behavior, with ΔE /k =86 K in a field of 1500 Oe.

Metal ions often influence the photoswitching efficiency of ap hotochromic system.T his article reports ao nedimensional polymer having cyclic azobenzenes coordinated to silver ions that are bridged by nitrates. The coordination polymer (CP-2)d isplays ap hotoresponsive behavior.T he switching ability in the polymer form was faster compared to the parenta zobenzene ligand withoutt he metal ions. Azobenzenes are reported to be poorlyc onducting. Here, although the azobenzene ligand does not show significant electronic mobility,t he coordination polymer (CP-2)d isplays am odest conductivity.T he conductance in the cis form of the polymer is significantly higher compared to the trans form. Upon exposure to visible light, the cis form undergoes photoisomerization to the trans form with ad rastic drop in the electronic mobility.T he trans form can be reverted to the cis form thermally or by using UV light.Thus,t his system offers ar eversible control of the conductivity using light.
