“…In this structure, the hydrogen bonds are weak with the D-A bond lengths varying from 2.846 to 3.508Å according to Brown [26] (Table 3). Mean values of distances C-C and C-N are, respectively, 1.512(2) and 1.509(2)Å. ese bond lengths are in agreement with those reported in the literature [27,28].…”

A new 2,6-bis aminomethyl piperidine decavanadate hydrate, (C7N3H20)2V10O28.4.21H2O, was synthesized by slow evaporation of a solution at room temperature. The molecular structure was investigated by single-crystal X-ray diffraction. In the crystal structure, the layers of decavanadate groups, organic cations, and water molecules are arranged parallel to the (010) plane. Also, the prepared compound has been analysed by FTIR spectroscopy and scanning electron microscopy (SEM). The crystal structure of the title compound is stabilized by hydrogen bonds and van der Waals interactions. The cohesion of the structure is ensured by O-H…O and N-H…O hydrogen bonds. The three-dimensional Hirshfeld surface (3D-HS) and the relative two-dimensional fingerprint plots (2D-FPs) of (C7N3H20)2V10O28.4.21H2O compound revealed that the structure is dominated by O…H/H…O (70.8%) and H…H (18.5%) contacts.

“…Cobalt diimine complexes have been employed as templates and nodes in a range of supramolecular assemblies, including catenanes (1)(2)(3)(4)(5)(6)(7)(8), rotaxanes (7,(9)(10)(11)(12)(13), and more extended multi-nuclear species (14)(15)(16)(17)(18)(19)(20). Such cobalt complexes make ideal building blocks in supramolecular chemistry on account of their ability to direct the formation of welldefined structures (21) and because of the reversible Co(II)/Co(III) redox chemistry that often manifests in these complexes.…”

Cobalt-diimine complexes have been used as structural and redox-active elements in a number of supramolecular assemblies. Frequently, it is necessary to functionalise the diimine ligand in order to incorporate it into a larger ensemble, and this can have a dramatic effect on the types of Co-diimine complexes that can form and their redox activity. Herein, we compare the solution-phase and redox chemistry of Co(II) complexes with 1,10-phenanthroline, 5,5′-dimethyl-2,2′-bipyridine and 2,9-dimethyl-1,10-phenanthroline (neocuproine), and show that in solutions containing Co(II) nitrate and neocuproine, the dominant species that forms is the mono-diimine complex [Co(neocuproine)(NO3)(CH3CN)2] +. The mono-neocuproine Co(II) complex is resistant to oxidation, either electrochemically or with iodine. We rationalise this behaviour by considering the steric constraints placed upon the metal centre by the bulky methyl substituents on the neocuproine ligand. Furthermore, from solutions of [Co(neocuproine)(NO3)(CH3CN)2] + , we isolate (and determine the structure of) crystals 2 of formula [Co(neocuproine)2(NO3)] + •[Co(neocuproine)(NO3)3] − for the first time. We believe that this work will help to guide the development of Co-diimine supramolecular assemblies by highlighting the extent to which substituents close to the N-donor atoms can affect which species form in solution, and their likely redox activity.

“…Accordingly, POVs have received considerable attention . Decavanadates, the preferable chemical stability compared to other {V x O y } n – clusters and easily obtained in aqueous solution, are seen as the excellent candidate for building units , . Thus, the relevant studies of structure and properties of polyoxovanadates remarkably increased by the decavanadate as building units connect with different transition‐metal ions or organic ligands , …”

Three new compounds, [Ln(H2O)8]2[V10O28]·8H2O [Ln = Ho (1), Tb (2)] and [Eu(H2O)8]2[V10O28]·9H2O (3), were successfully synthesized by evaporating the mixture of K6V10O28·10H2O and LnCl3·6H2O. Notably, three vanadates are composed of [Ln(H2O)8]3+ cation, decavanadates ([V10O28]6–) anion. Meanwhile, free water molecules generate different type water clusters to connect [V10O28]6– anions and coordination cations to form 3D supramolecular structure. The fluorescence measurements reveal that characteristic photoluminescence of TbIII and EuIII is quenched in presence of [V10O28]6–, then the impacts of variational decavanadates ions concentration on the fluorescence intensities of LnCl3 (Ln = Tb, Eu) systems and different acetate solution [M(CH3COO)2; M = Ni, Cr, Cu, Co, Zn] on fluorescence intensities of Ln‐decavanadates (Ln = Eu, Tb) systems are investigated.
