“…So far, hydrazone-based metal complexes have received considerable attention from chemists in many applications such as chromogenic reagents in the spectrophotometric determination of transition-metal ions, metal extracts and biologically active compounds [ 9 ]. They have also been demonstrated to possess diverse pharmacological properties [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ], catalytic properties [ 18 , 19 ], adsorption properties [ 20 , 21 ], electrochemical properties [ 22 ], luminescent properties [ 23 , 24 ], etc.…”

Four complexes, [Cu4L2(OCH3)2(CH3OH)2]·2H2O (1), [Zn2L2Cl4]·2H2O·2CH3OH (2), [Hg2L2Br4]·4CH3OH (3), and {[CdL2Cl2]·4H2O·4CH3OH}n (4), have been synthesized and characterized from a bis(pyridylhydrazone) ligand (L) with copper(II), zinc(II), mercury(II) or cadmium(II), respectively. Complex 1 exists as a centrosymmetric tetranuclear dimer with L as deprotonated tridentate ligand. Complexes 2 and 3 exist as centrosymmetric metallamacrocycles with L as bidentate ligand. Complex 4 exists as a 1D looped-chain coordination polymer. The thermal stabilities and vapor adsorption properties of the four complexes were investigated as well.

“…In Hg 1 and Hg 2 , the μ 2 ‐X bridging between the two Hg atoms generates an Hg‐(X 2 )‐Hg parallelogram, [ 24 ] with Hg–Cl1 and Hg–Cl1# bond lengths of 2.666(8) and 2.671(9) Å in Hg 1 , whereas Hg–Br1 and Hg–Br1# are 2.760(10) and 2.751(9) Å in Hg 2 . In Hg 3 , only one iodo group I1 bridges between the two Hg centers with Hg2⋯I1 interaction of 3.5153(5) Å.…”

Three new Hg(II) complexes with general formula [Hg(L)X2]2 (X = Cl (Hg 1), Br (Hg 2), and I (Hg 3)) have been synthesized using the novel ferrocenyl functionalized ligand 3‐ferrocenyl methyl‐thiazolidine‐2‐thione (L). The ligand (L) and the complexes have been characterized by Fourier transform infrared (FTIR), multinuclear nuclear magnetic resonance (NMR), electronic absorption, photoluminescence spectroscopies, and single crystal X‐ray diffraction. The single crystal X‐ray diffraction studies indicated that Hg 1 and Hg 2 are centrosymmetric dimers with distorted tetrahedral geometry around the Hg(II) centers generated by the two bridging halides, a terminal halide, and an exocyclic sulfur of ligand. Hg 3 possess two monomers with trigonal planar geometries around Hg(II), which are further held by weak Hg⋯I interactions. Variation in geometrical parameters have been attributed to differences in the nature of the halide donors attached to the Hg(II). The cyclic voltammetry experiments for all the compounds suggested their quasi‐reversible redox properties. Also, the photoluminescent investigation for Hg 1 and Hg 2 indicated medium strong photoluminescence emission at ~500 nm arising due to metal‐to‐ligand charge‐transfer (MLCT) transitions of the ferrocenyl moiety. The solid‐state structure of complexes are stabilized by varied interactions, namely, C–H⋯C and bifurcated H⋯Cl⋯H interactions in Hg 1, C–H⋯C, C–H⋯S, S⋯C (Cp), and C–H⋯Br interactions in Hg 2 and C–H⋯C, C–H⋯S, and C⋯S interactions in Hg 3. The nature and percentage contribution of all these interactions have been studied by the Hirshfeld surface analyses. The interaction energies for the dimers of all four compounds have been assessed with the help of density functional theory (DFT) and quantum theory of atoms in molecules (QTAIM).

“…The adsorption isotherms show a typical type III nature with the largest quantity adsorbed for complexes 1 and 2 are 2.0 and 2.2 mmol g À 1 , which are similar to the complexes reported in previous reports. [35,36] Although the amount of methanol vapor adsorbed by the complexes is not as large as MOFs materials that reported in the literature, [37,38] it is still meaningful for the two coordination polymers to be potential materials as adsorbent of methanol vapor.…”

Two complexes, [HgL 1 Cl 2 ] n (1) and [Hg 2 (L 2) 2 Cl 4 ] n (2), have been synthesized and characterized from two dipyridylamide ligands (L 1 and L 2) with mercury(II) chloride, respectively. The two complexes exist as 1D coordination polymers but exhibit different architectures with slightly adjusted 3-and 4-position of nitrogen atom in the pyridyl rings from the two ligands. In complex 1, the mercury(II) center is four-coordinated with distorted tetrahedral geometry in 1D-chain structures. In complex 2, the mercury(II) center is five-coordinated with distorted square pyramidal geometry in the 1D-looped structures. The thermal stabilities and vapor adsorption properties of the two complexes were investigated as well.
