This manuscript addresses the synthesis, structural characterization and optical properties of a 1D coordination polymer (CPs) and 2D and 3D Metal-Organic Frameworks (MOFs) obtained from lanthanide metals, 3-hydroxinaftalene-2,7-disulfonic acid (3-OHNDS) and two different phenanthroline derivates as ancillary ligands. The first is a family of 2D compounds with formula [Ln(3-OHNDS)(H2O)2], where...
Six related organo–chalconium silver(I) coordination complexes, including two examples of rare organotellurium-silver coordination, have been prepared and structurally characterised by X-ray crystallography. The series of 5-bromo-6-(phenylchalcogeno)acenaphthene ligands L1–L3 [Acenap(Br)(EPh)] (Acenap = acenaphthene-5,6-diyl; E = S, Se, Te) were independently treated with silver(I) salts (AgBF4...
Assembling nanoparticles into one-dimensional (1D) nanostructures with precisely controlled size and shape renders the exploration of new properties and construction of 1D miniaturized devices possible. The physical properties of such nanostructures depend heavily on the size, chemical composition, and surface chemistry of nanoparticle constituents, as well as the close proximity of adjacent na...
Synthesis and characterization of nanowires Hausmannite (Mn3O4) by solid-state thermal decomposition
In this study, we synthesis one-dimensional (1D) manganese(III) Schiff base coordination polymer [Mn(Brsalophen)(μ1,3-N3)]n by reaction of MnCl2·6H2O and tetradentate Schiff base ligand Brsalophen at the presence of NaN3 in methanol and characterized by elemental analyses (CHN) and FT-IR spectroscopy. It was used as a new precurs...
The synthesis and mechanical properties of a new class of coordination polymer based materials, amorphous coordination polymer sol-gels and xerogels, is presented.
Using ligands based on either an acetylacetonate or a dipyrrin moiety appended with pyridyl groups, a series of novel heteroleptic copper(II) and cobalt(III) complexes combining both chelate units such as (acacpy(2))Cu(dpm-py) and (acacpy(2))Co(dpm-py)(2) (acacpy(2) = 1,3-bis(4-pyridyl)-1,3-propanedionate; dpm-py = 5-(4-pyridyl)dipyrrin) have been prepared and fully characterized. These two com...
Abstract Dithiolene based coordination polymers, due to their coordinative bonds with covalent character, feature interesting electrical properties. We present the syntheses and crystal structures of three polymers on ligand 2,3‐pyrazinedithiolate (pdt 2− ) Ag + Zn 2+ ions. 2D [Ag 3 (Hpdt) 2 ](ClO 4 ( 1 Cs 1D [Ag(pdt)] ⋅ CH OH short Ag⋅⋅⋅Ag distances, 3D [Zn(pdt)] has a network structure is sta...
