Unprecedented layered coordination polymers of dithiolene group 10 metals: magnetic and electrical properties

Abstract: One-pot reactions between Ni(ii), Pd(ii) or Pt(ii) salts and 3,6-dichloro-1,2-benzenedithiol (HSC6H2Cl2SH) in KOH medium under argon lead to a series of bis-dithiolene coordination polymers. X-ray analysis shows the presence of a common square planar complex [M(SC6H2Cl2S)2](2-) linked to potassium cations forming either a two-dimensional coordination polymer network for {[K2(μ-H2O)2(μ-thf)(thf)2][M(SC6H2Cl2S)2]}n [M = Ni () and Pd ()] or a one-dimensional coordination polymer for {[K2(μ-H2O)2(thf)6][Pt(SC6H2Cl… Show more

“…This is due to the moderate-to-low stability of the coordination compounds, showing volatile molecules of solvent weakly coordinated to the metal center. This behavior has been previously reported for related compounds [ 16 , 18 , 19 , 20 ].…”

“…The chemistry of transition metals with dithiolene derivatives is a research field of high interest due to the outstanding physical properties that these compounds can show, as well as their wide structural diversity [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. The dithiolenes are known as “non-innocent” ligands since they can form complexes with metals in different oxidation states giving rise to a rich redox chemistry of both the ligand and the metal center [ 16 ], leading to the formation of neutral, monoanionic and dianionic dithiolene derivatives [ 17 ]. We have previously studied the influence of several parameters, such as the nature of the dithiolene ligands, the size of the counter cations, the influence of crystallization conditions, as well as the type of iron precursor used, in the synthesis of a series of coordination polymers (CPs) containing the dianionic entities [Fe 2 (SC 6 H 2 X 2 S) 4 ] 2− (X = Cl or H) and [M 2 (µ-L) n ] 2+ (M = alkali metal) as counter-cations [ 18 , 19 ].…”

“…Some of these compounds indicate that the sulfur donor atoms of the [Cu(SC 6 H 2 Cl 2 S) 2 ]entity and even the chloro substituents are able to anchor additional metal centres, specially softer ones, promoting a further polymerization. The electrical studies carried out in this work with 3 and 4 CPs as compare with those previously reported for related CPs based on metal-dithiolene entities bridged by alkali complexes, 20,[35][36][37] suggest that the electrical conductivity is limited to relatively low values, 10 -6 -10 -9 σ•cm -1 , probably because of the limitation in electric current passes through the group 1 metal complexes. These results indicate that the formation of electrically conductive of CPs based on metaldithiolene entities require more efficient connectors.…”

“…Indeed, some of the examples giving rise to CPs are: 27 Additionally, a microporous framework, Cu[Ni(pdt)2] (pdt2 -=pyrazine-2,3-dithiolate) showing electrical conductivity, doping, and redox behavior have been reported. 28 On the other hand, we have recently reported 29 rings have been described. [30][31][32][33] However, as far as we know, compound [K2Fe(SC6H5)4]n 34 is the only example of an organometallic polymer made up with transition metals aromatic thiolate entities linked by alkali complexes through σand π-interactions.…”
