“…In particular, the remaining four Ag–Ag vacancies on the Ag 10 ring that are not coordinated with CF 3 COO – are each coordinated with one dpphS 2 , and the adjacent clusters are further extended into 1D chains bridged by dpphS 2 (Figure d). There are few studies on the synthesis and application of dpphS 2 , and Ph 3 P was often used to obtain it through designable organic reaction. − However, we have facilitated the redox reaction through high-temperature solvothermal conditions to obtain dpphS 2 containing 0-valent S as well as SO 4 2– template. Different from the previous Ag–P coordination, the diphosphine ligands of 5 are coordinated with S(0) atoms, while S(0) atoms use μ 2 coordination modes to connect Ag atoms, and the bond lengths of Ag–S(0) are in the range of 2.620(4)–2.676(3) Å (Table S8).…”

The diphosphine ligands can act as auxiliary ligands for the thiol ligands to generate novel silver clusters. Here, we report five silver thiolated clusters protected by diphosphine ligands, namely, [Ag 11 ( i PrS) 9 (dppm) 3 ](BPh 4 ) 2 (1, dppm = bis-(diphenylphosphino)methane), S@Ag 26 ( i PrS) 16 (CF 3 COO) 8 (dpph) 2 •3DMF (2, dpph = 1,6-bis(diphenylphosphino)hexane), S@Ag 26 ( i PrS) 16 (CF 3 COO) 8 (dpppe) 2 •2DMF (3, dpppe = 1,5-bis(diphenylphosphino)pentane), AgS 2 @Ag 24 ( t BuS) 18 (dpppe) 2 (BF 4 ) 3 (4), and [SO 4 @Ag 20 ( i PrS) 10 (CF 3 COO) 8 (dpphS 2 ) 2 ] n (5, dpphS 2 = 1,6-bis(diphenylphosphino)hexane disulfide). Their structures were characterized by single-crystal X-ray diffraction, which revealed that 1 presents a triangular structure covered by three diphosphine ligands, and there are strong C−H•••π interactions between clusters and between clusters and counterions. Clusters 2 and 3 are olive-shaped structures, and cluster 4 is a box-type structure. Clusters 2−4 all have two diphosphine ligands at both ends. Cluster 5 is a chainlike structure connected by dpphS 2 . Among them, cluster 1 exhibits photoluminescence (PL) properties, and the emission of its solution phase is red-shifted compared to the crystalline state.
