Solvothermal Syntheses and Crystal Structures of the Two New Polymeric Compounds [Ce(C₄N₃H₁₃)₂(μ₃‐SbS₄)]_n and [La(C₄N₃H₁₃)₂(μ₄‐Sb₂S₅)(μ₃‐SO₄)]_n 

Abstract

The two new one-dimensional polymeric compounds [Ce(C 4 N 3 H 13 ) 2 (μ 3 -SbS 4 )] n (1) and [La(C 4 N 3 H 13 ) 2 (μ 4 -Sb 2 S 5 )(μ 3 -SO 4 )] n (2) were synthesized under solvothermal conditions. In the first compound, the unique Ce 3+ cation is surrounded by six nitrogen atoms of the amine ligands and by three sulfur atoms of the thioantimonate(V) anion. The CeN 6 S 3 polyhedron may be described as a distorted tricapped trigonal prism. The prisms are interconnected by [SbS 4 ] 3anions, which act in a μ 3 -binding mode yielding a chain running along [100]. An extended hydrogen-bonding network leads to the formation

From Zero- to Three-Dimensional Thioantimonates: [Ni(aepa)2]3Sb6S12 (aepa = C5H15N3 = N-(aminoethyl)-1,3-propandiamine), Containing the Unique [Sb6S12]6– Cyclic Anion, [Ni(aepa)2]6(Sb3S6)2(SO4)3·2H2O, with Isolated [Sb3S6]3– anions and [Ni(aepa)2]Sb4S

“…The Sb–S bond lengths of the SbS 3 moiety (2.3982(1)–2.4813(1) Å) are shorter than in the SbS 4 unit with two long (2.6885(2) and 2.8021(2) Å) and two short (2.3987(1) and 2.4580(2) Å) bonds (Table 3, Supporting Information). This bonding pattern is typical for SbS 4 groups and was observed in several other thioantimonates(III). ,,,,, We note that the Sb–S bonds in the [Sb V S 4 ] 3– anion are much shorter and scatter around 2.3 Å. − ,− Interestingly, no further Sb···S contacts below 3 Å are found in the structure of 3 .…”

Solvothermal Synthesis and Characterization of a Series of Lanthanide Thiostannates(IV): The First Examples of Inorganic–Organic Hybrid Cationic Lanthanide Thiostannates(IV)

“…Notably, the coordinatively unsaturated dinuclear lanthanide complex as bridging nodes within the chalcogenidometalates of the group 13–15 elements is uncommon, and normally they occur mononuclear. ,, For instance, the 1-D La–Sb–S chain, [La(en) 3 (μ 3 -SbS 4 )] n , is formed by the interconnection of [La(en) 3 ] 3+ complexes and multidentate [SbS 4 ] bridging units. The 1-D La–Sn–Se chain in [{La(dien) 2 } 4 (μ 4 -Sn 2 Se 9 )(μ-Sn 2 Se 6 )] n , is constructed by the linkage of {La(dien) 2 } 3+ complex, [Sn 2 Se 9 ] and [Sn 2 Se 6 ] units.…”
