Synthesis, crystal structures of [M(tepa)]2(μ2-Sn2Se6)(M=Fe and Co), showing a selenidostannate bridge for transition metal complex cations

Two Novel Adamantane‐Like Thio/Selenidogermanates with Complex Cations

“…Tetradentate teta (or tren) or pentadentate tepa molecules leave at least one coordination site free at the M 2+ ion enabling bond formation to the sulfur/selenium atoms of the Ge x Q y n – anion, such as [{Co(tepa)} 2 (μ‐Ge 2 S 6 )],8 and [{ M (tepa)} 2 (μ‐Ge 2 Se 6 )]( M = Mn, Fe) 8. A similar phenomenon is observed in chalcogenidostannates [{Co(tren)} 2 (μ‐Sn 2 S 6 )],14 [{Ni(tren)} 2 (μ‐Sn 2 S 6 )],14 [{ M (tepa)} 2 (μ‐Sn 2 S 6 )] ( M = Fe, Co, Ni, Mn),15,16 and [{ M (tepa)} 2 (μ‐Sn 2 Se 6 )] ( M = Fe, Co, Mn) 16,17. However, both [Ni 2 (μ‐teta)(teta) 2 ]Ge 4 S 10 ·H 2 O ( 1 ) and [Ni(teta) 2 ] 2 Ge 4 Se 10 ·0.5H 2 O ( 2 ) were obtained from a mixture of NiCl 2 ·6H 2 O, GeO 2 , S (or Se) and H 2 O in the presence of teta amine under mild solvothermal conditions.…”

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

“…The dual roles of [TM(L 4 )] n+ complexes in modifying the inorganic maingroup metal chalcogenide frameworks contribute to increased complexity and functionality of hybrid chalcogenides. In contrast, the L 5 -dentate chelating amine (tepa, for example) prefer to coordinate to TM ion to form [TM(L 5 )] n+ complex with only one free coordination site of the TM ion, which usually display structuredecorating groups in the chalcogenides, such as compounds 4a, 4b and several similar compounds in the literature [28,[70][71][72][73][74][75].…”

Solvothermal Syntheses and Characterization of a Series of New Selenidostannates with Lanthanide Complexes as Counterions

“…Unsaturated TMCs that act as either decorating groups or bridging groups can bond directly to [Sn 2 Q 6 ] 4-anions to form a new class of organic hybrid chalcogenidostannates, as exemplified by [{Mn(en) 2 } 2 (l-en) (l-Sn 2 S 6 )] [11], [{M(tren)} 2 (l-Sn 2 S 6 )] (tren = tris(2-aminoethyl)amine; M = Ni and Co) [2a], and [M(tepa)] 2 (l-Sn 2 Se 6 ) (tepa = tetraethylenepentamine; M = Fe, Co, Mn) [12,13]. Compared with the overwhelming chalcogenido-stannates containing TMCs, lanthanoid chalcogenidostannates are less explored under mild solvothermal conditions [14][15][16], mainly because they are comparatively unstable with respect to heat, water, oxygen, and light [17].…”
