Anion Templated Synthesis of Silver(I)-Ethynide Dithiophosphate Clusters
No full textReaction
of AgCC<sup><i>t</i></sup>Bu with (EtO)<sub>2</sub>PS<sub>2</sub>Na at room temperature leads to the isolation
of two new silver(I)-ethynide compounds incorporating the dithiophosphate
ligand, namely, {CO<sub>3</sub>@(Ag<sub>3</sub>)<sub>4</sub>(CC<sup><i>t</i></sup>Bu)<sub>4</sub>(EtO)<sub>2</sub>PS<sub>2</sub>]<sub>6</sub>}·0.5H<sub>2</sub>O (<b>1</b>) and {(CO<sub>3</sub>)<sub>2</sub>@Ag<sub>26</sub>(CC<sup><i>t</i></sup>Bu)<sub>16</sub>[(EtO)<sub>2</sub>PS<sub>2</sub>]<sub>4</sub>}·2(OH)·4MeOH·6H<sub>2</sub>O (<b>2</b>). Besides,
we obtain another three silver(I)-ethynide clusters S@Ag<sub>11</sub>(CC<sup><i>t</i></sup>Bu)<sub>2</sub>[(EtO)<sub>2</sub>PS<sub>2</sub>]<sub>7</sub> (<b>3</b>), {S@Ag<sub>14</sub>(CCPh)<sub>8</sub>[(EtO)<sub>2</sub>PS<sub>2</sub>]<sub>4</sub>(TMEDA)<sub>2</sub>}·5MeOH (<b>4</b>), and {S@Ag<sub>14</sub>(CCPh)<sub>8</sub>[(<sup><i>i</i></sup>PrO)<sub>2</sub>PS<sub>2</sub>]<sub>4</sub>(TMEDA)<sub>2</sub>}·7CH<sub>3</sub>OH (<b>5</b>), with AgCCR (R= <sup><i>t</i></sup>Bu, Ph) and (RO)<sub>2</sub>PS<sub>2</sub>Na (R= Et, <sup><i>i</i></sup>Pr) as the starting materials. Complexes <b>1</b>–<b>2</b> are templated by a carbonate anion in situ
generated from the fixation of atmospheric CO<sub>2</sub> in a basic
TMEDA-containing solution, and TMEDA can also lead to the disassembly
of dithiophosphate to give a sulfide ion as the template for the generation
of <b>3</b>–<b>5</b>
Chiral Copper(I) Halide Clusters and Coordination Chain Exhibiting Photoluminescence and Circularly Polarized Luminescence
No full textThe
synthesis of chiral atomically precise metal clusters is hindered
by the challenge of achieving desirable crystallinity, and the investigation
of chiral alkynyl copper(I) halide compounds with circularly polarized
luminescence (CPL) responses remains a relatively unexplored area.
In this study, we successfully synthesized five gram-scale pairs
of enantiomers by utilizing chiral proparylbenzylamine ligands and
copper halides as precursors. Notably, these enantiomers incorporate
ionic, coordinate bonds, and C–H···π interactions
to significantly enhance their stability and crystallinity. Derived
from either Br– or I–, the enantiomers
exhibited distinct skeletal characteristics, resulting in four different
structural types. A thorough analysis was undertaken to elucidate
the origins of the chirality within each of these structural motifs.
Remarkably, all of the enantiomers displayed photoluminescence and
mirror-image circular dichroism (CD) responses. Of particular interest,
the one-dimensional (1D) compound R/S-1 exhibited pronounced CPL activities
and an anisotropy factor (glum) of ∼0.007
in its crystalline state. This investigation contributes to the understanding
of structure–property relationships in chiral compounds and
offers a new strategy for designing materials with targeted functionalities
