Chiral copper-hydride nanoclusters: synthesis, structure, and assembly

Abstract

An effective strategy is developed to synthesize a novel and stable layered Cu nanocluster in one pot reduction method. The cluster, with molecular formula of [Cu14(tBuS)3(PPh3)7H10]BF4 which has been unambiguously...

Carboxylate-Protected “Isostructural” Cu20 Nanoclusters as a Model System: Carboxylate Effect on Controlling Catalysis

“…The four regular Cu 3 triangles can be divided into two groups according to their positions and sizes: the Cu 3 triangles ( d Cu–Cu = 6.8632 Å) close to the Se@Cu 6 kernel are larger than those far away ( d Cu–Cu = 4.2528). The metal frame of the Cu 20 -1 cluster thus presents a layer-by-layer stacking pattern based on the Cu 3 regular triangles (Figure e), reminiscent of the structure of [Cu 14 ( t BuS) 3 (PPh 3 ) 7 H 10 ] + reported recently . Alternatively, the structure of the cluster resembles a rotating six-awn star in the top view (Figure f).…”

“…The metal frame of the Cu 20 -1 cluster thus presents a layer-by-layer stacking pattern based on the Cu 3 regular triangles (Figure 2e), reminiscent of the structure of [Cu 14 ( t BuS) 3 (PPh 3 ) 7 H 10 ] + reported recently. 83 Alternatively, the structure of the cluster resembles a rotating six-awn star in the top view (Figure 2f). Featuring several types of organic ligands, we also analyze the coordination structures of the Cu 20 -1 nanocluster.…”

Large-scale synthesis, mechanism, and application of a luminescent copper hydride nanocluster

“…As for the surface protectingligands, each PPh 2 Py ligand bridges two Cu atoms through Cu-P and Cu-N coordination (average distance: 2.22 Å and 2.06 Å, respectively), which is consistent with those reported in other copper nanoclusters. 28,44,45 Each Cl atom coordinates with two Cu atoms with Cl-Cu bonds (average distance: 2.435 Å). All these results demonstrate that the whole structure of Cu 4 H NC possesses high rigidity, which may be responsible for its strong photoluminescence.…”

Seven Nuclei Cluster of Copper: Synthesis, Structure and Assembly

“…[1f,2b,h,3a,f,6] The reports include the assembly of copper-clusters of Cu 8 (SN) 4 ( t BuS) 4 (SN is 4-(4-Pyridinyl) thiazole-2-thiol) into a framework, [7] the control of the chiral assembly of luminescent copper(I) clusters of [Cu 5 (S t Bu) 6 ] À , [8] and the formation of chiral nanostructures from self-assembly of [Cu 14 ( t BuS) 3 (PPh 3 ) 7 H 10 ] + . [9] It is interesting to note that the studies on the assembly chemistry of copper halide clusters are increasing as well, as the family of compounds often exhibits polymeric structures and good photophysical as well as photochemical properties. [10] In this regard, we wonder whether more copper clusters, with novel composition, molecular structure, and assembly structure, can be gained so that the structural dedication of larger nanostructures can be highlighted.…”
