Ortho‐Chalcogenostannates as Ligands: Syntheses, Crystal Structures, Electronic Properties, and Magnetism of Novel Compounds Containing Ternary Anionic Substructures [M4(μ4‐Se)(SnSe4)4]10− (M=Mn, Zn, Cd, Hg), ${{{\hfill 3\atop \hfill \infty }}}${[Hg4(μ4‐Se)(SnSe4)3]6−}, or ${{{\hfill 1\atop \hfill \infty }}}${[HgSnSe4]2−}

“…Fitting of the magnetic susceptibility revealed a significant antiferromagnetic interaction ( J/k B =−12.1(2) K) between the Mn II ions through the Se bridge. The results show that the ground state of the [Mn 4 (μ 4 ‐Se)(SnSe 4 ) 4 ] 10− cluster is a singlet with a first excited state ( S =1) at 24.2 K. Compound 3 is to our knowledge the first compound with an [Mn 4 Se] fragment to be investigated by magnetic measurements, but antiferromagnetic coupling between tetrahedrally coordinated Mn centers was also observed in K 2 [MnSnS 4 ],6c albeit based on a two‐dimensional Mn/Sn/S network with μ‐bridging sulfur ligands instead of μ 4 ‐bridging ligands .…”

“…Ternary M/E′/E compounds that have been reported to date range from molecular species such as [Na(2,2,2‐crypt)][{(C 5 Me 5 )(CO) 2 MnSn) 3 S 4 }Na(THF) 3 ]3 and [(PhSnS 3 ) 2 (CuPPhMe 2 ) 6 ],4 through a large number of mesostructured phases such as Rb 3 [AgGe 4 Se 10 ]⋅2 H 2 O,5 (CP) 3 [Fe 4 S 4 Ge 4 S 10 ] (CP=cetylpyridinium),6a and (CP) x [Pt y Sn 4 Se 10 ] ( x =1.9–2.8, y =0.9–1.6),6b to several solid‐state phases such as K 2 [MnSnS 4 ]6c and Ba[Cu 6 Ge 2 S 8 ] 7…”

“…Such materials can be synthesized in principle by two routes: formation of the ternary compounds from separate sources of M, E′, and E during the reaction,3–5, 6c, 7 or by reaction of binary precursors 6a. b, d The latter additionally allows us to study the stability of the binary species under the given reaction conditions, for example, the reaction behavior of E′/E reactants in the presence of reactive transition metal complexes.…”

Crystal Structures and Magnetic Properties of Quaternary Manganese Sulfides, BaLn2MnS5 (Ln=La, Ce, and Pr)

“…In a quaternary manganese sul"de, Cu MnSnS , the MS (M"Mn, Cu, Sn) tetrahedra share their corners and the Mn ions form a bodycentered tetragonal lattice (3). For K MnSnS , cornersharing MS tetrahedra (M"Mn and Sn) form M S tetrameric clusters, and the tetrameric clusters and K ions crystallize in a monoclinic structure (4).…”

Five dimeric thiogermanates with transition metal complexes of multidentate chelating amines: Syntheses, structures, magnetism and photoluminescence

“…The design and syntheses of new inorganic-organic hybrid chalcogenide materials have attracted considerable interest during the past decade, not only for their intriguing structural chemistry [1][2][3][4][5][6][7], but also for many potential applications as semiconductors, storage materials, and magnetic materials [8][9][10][11][12][13][14][15]. Under the relatively mild hydro(solvo)thermal conditions, the use of alkylammonium cations, organic amines as well as transition metal complexes (TMCs) as templates has been proved to be very effective in the syntheses of chalcogenides [4,[16][17][18][19][20].…”
