enantiomeric excess of the RhIII molecules induced by chiraltransfer from d-penicillamine. 1 can accommodate/release external Ag+ ions and replace inner Ag+ ions by Cu+ ions. The study demonstrates that a thiolato metalcomplex and sulfur-containing amino acid can be used as cluster-surface-protecting and sulfide-supplying regents, respectively, for creating chiral, water-soluble, structurally precise silver

Single‐crystal X‐ray analysis revealed that complexes 1 and 2 are Ag48 and Ag51 coordination chain polymers, while 3 contains a discrete Ag48 cluster, in which three different kinds of silver(I) thiolatecluster shells enclose three different phosphonate‐functionalized silver(I) cluster cores, respectively. The structures of clusters in 1–3 feature three

new high-nuclearitysilver(I) sulfide-ethynide-thiolate clusters, in which silver(I) aggregates tBuC≡C⊃Ag3, tBuC≡C⊃Ag4, and 2tBuC≡C⊃Ag7 are bridged by tBuS– ligands to engender respective silver(I) ethynide-thiolate clusters functioning as integral shell components, which are supported by phosphonate ligands. In each silver(I) sulfide-ethynide-thiolate cluster, a different encapsulated silver sulfide
20‐tetra(4‐pyridyl)porphyrin (TPyP‐H2) ligands to afford a robust 2D metal–organic framework (Ag27‐MOF). This silver cluster‐assembled material serves as a highly efficient heterogeneous catalyst for the cyclization of both terminal and internal propargylamines with CO2 under atmospheric pressure. Density functional theory (DFT) calculations illustrate that the high catalytic activity and broad substrate

Constructing silver(I)–thiolate clusters from simple building blocks usually involves elusive self-assembly processes and remains a long-standing challenge. In this work, we report 6 silver(I)–thiolate clusters protected by pyridines, namely, [Ag3(tBuS)2(Py)(NO3)]n (Py = pyridine) (1), [Ag10(tBuS)6(Py)6(CF3CO2)4]·3Py (2), [Ag12(iPrS)6(Py)8(NO3)6]·2H2O (3), Ag12(iPrS)6(Py)8(CF3CO2)6 (4), Ag12(iPrS)6(4-ap)6(NO3)6
从简单的结构单元构建银(I)-硫醇盐簇通常涉及难以捉摸的自组装过程,并且仍然是一个长期的挑战。在这项工作中,我们报告了6个由吡啶保护的银(I)–硫醇盐簇,即[Ag 3(t BuS)2(Py)(NO 3)] n(Py =吡啶)(1),[Ag 10(t BuS)6(Py)6(CF 3 CO 2)4 ]·3Py(2),[Ag 12(i PrS)6(Py)8(NO 3) 6 ]·2H 2 O( 3),Ag 12( i PrS) 6(Py) 8(CF 3 CO 2) 6( 4),Ag 12( i PrS) 6(4-ap) 6(NO 3) 6(4-ap = 4-氨基吡啶)( 5)和[Ag 50 S 13( t BuS) 20(Py) 12 ]·4BF 4 ·4Py·4CH 3 OH·2H2 O( 6)。X射线晶体学分析表明,六种簇是由四种类型的结构嵌段构成的,包括PyAg( t BuS) 2单体,Py
