A novel 2D net-like supramolecular polymer constructed from Ln6Cu24 node and trans-Cu(Gly)2 bridge

A 2D net-like lanthanide-copper heterometallic supramolecular network {Ln6Cu27} 1 was synthesized with Ln6Cu24 octahedral cluster as the node and trans-Cu(glycinato)2 group as the linker. The compound represents the first example of 2D polymer with high-nuclear 3d–4f heterometallic cluster as the node.

A new strategy for the preparation of H2tdet intermediate–synthesis and crystal structure of {α-[Sn(edt)2(tdet)]}·{β-[Sn(edt)2(tdet)]} (edt = ethane-1,2-dithiolate, tdet=diethylenetrithiolato)

Abstract A mononuclear tin(IV) complex {α-[Sn(edt)2(tdet)]}·{β-[Sn(edt)2(tdet)]} was synthesized by the reaction of Sn(edt)2 and NaOH under hydrothermal conditions and characterized by X-ray structure analysis. Under hydrothermal conditions, two edt ligands turned into one tdet and this provides a new strategy for the preparation of H2 tdet from cheap material. In the complex, the distances of Sn–S (thiolate) are about 2.4 A, but the distances of Sn–S (thioether) are about 2.8 A. Two isomers were found in the molecule.
