“…As expected on the basis of different coordination numbers, the Ag(1)−S [average 2.548 Å] and Ag(1)−P [2.388(2) Å] distances are substantially shorter than the corresponding distances at the Ag(2) center [Ag(2)−S, 2.690 Å; Ag(2)−P, 2.461 Å]. These Ag−S and Ag−P distances are typical of those of trigonal and tetrahedral silver compounds 4 Molecular structure of 6 at the 50% probability level.…”

The coordination chemistry of chelating silanedithiolato ligands has been investigated on Fe(II), Co(II), Pd(II), Cu(I), and Ag(I). Treatment of M(OAc)(2) (M = Fe, Co, Pd) with cyclotrisilathiane (SSiMe(2))(3) in the presence of Lewis bases resulted in formation of Fe(S(2)SiMe(2))(PMDETA) (1), Fe(S(2)SiMe(2))(Me(3)TACN) (2), Co(S(2)SiMe(2))(PMDETA) (3), and Pd(S(2)SiMe(2))(PEt(3))(2) (4) (PMDETA = N,N,N',N',N' '-pentamethyldiethylenetriamine; Me(3)TACN = 1,4,7-trimethyl-1,4,7-triazacyclononane). The analogous reactions of M(OAc) (M = Cu, Ag) in the presence of PEt(3) gave rise to the dinuclear complexes M(2)[(SSiMe(2))(2)S](PEt(3))(3) [M = Cu (5), Ag (6)]. Complexes were characterized in solution by (1)H, (31)P[(1)H], and (29)Si[(1)H] NMR and in the solid state by single-crystal X-ray diffraction. Mononuclear complexes 1-3 have a four-membered MS(2)Si ring, and these five-coordinate complexes adopt trigonal-bipyramidal (for the PMDETA adducts) or square-pyramidal (for the Me(3)TACN adduct) geometries. In dimer 6, the (SSiMe(2))(2)S(2)(-) silanedithiolato ligand bridges two metal centers, one of which is three-coordinate and the other four-coordinate. The chelating effect of silanedithiolato ligands leads to an increase in the stability of silylated thiolato complexes.

“…These very short Ag−Ag interatomic distances are shorter than the comparable distance in the phosphine adduct [{Ag(SnB 11 H 11 )PPh 3 } 2 ] 2− [2.7160(4) Å] and the Ag−Ag distance in metallic silver [2.89 Å] . Furthermore, the found Ag−Ag contacts belong to the group of the shortest values known in the literature. − In [{Ag(SnB 11 H 11 )PEt 3 } 3 ] 3− we found, with 2.6326(10) Å, an example with a shorter Ag−Ag distance, and in diaryltriazene- and amidinate-bridged dimers the Ag−Ag bond length is only a little bit longer. − In the complexes 5 − 7 an interesting distortion in the solid state was detected: the plane through the nitrogen atoms is not perpendicular to the plane through the tin and silver atoms (Figure ). Probably due to packing forces, the angle between the best planes through the nitrogen atoms and the four Sn and Ag atoms ranges from 65° to 76°.…”

The reaction of the tin nucleophile stanna-closo-dodecaborate [SnB 11 H 11 ] 2-with silver electrophiles resulted in the formation of silver-tin complexes. Depending on the respective co-ligands, a dimer, a tetramer, a polymer, and a three-dimensional network structure were characterized. With bipyridine and phenanthroline, dimeric complexes exhibiting very short Ag-Ag interatomic distances were isolated. With t-BuNC and pyridine, tetranuclear clusters showing tetrahedral geometry were crystallized. From the reaction of the silver salt [Et 4 N] 8 [Ag 4 (SnB 11 H 11 ) 6 ] with the bridging ligand 1,4-diisocyanobenzene (DIB) a linear polymeric coordination compound was formed, and a three-dimensional network structure was the product from the reaction of 1,4-diisocyanobenzene with the silver salt [Me 4 N][Ag(SnB 11 H 11 )]. The coordination compounds were characterized by X-ray crystal structure analysis and elemental analysis. In the case of the threedimensional network material {[Me 4 N] 4 [Ag 4 (SnB 11 H 11 ) 4 (DIB) 6/2 ]} n (12) a single crystal to single crystal solvent exchange was found.

The past decades have witnessed great advances in controllable synthesis, structure determination, and property investigation of metal nanoclusters. Selenolated nanoclusters, a special branch in the nanocluster family, have attracted great interest in these years. The electronegativity and atomic radius of selenium is different from sulfur, and thus the selenolated nanoclusters are anticipated to display different electronic/geometric structures and distinct chemical/physical properties relative to their thiolated analogues. This review covers the syntheses, structures, and properties of selenolated nanoclusters (including Au, Ag, Cu, and alloy nanoclusters). Ligand effects (between SeR and SR) on nanocluster properties, including optical absorption, stability, and electrochemical properties, are disclosed as well. At the end of the review, a scope for improvements and future perspectives of selenolated nanoclusters is highlighted. The review hopefully opens up new horizons for cluster scientists to synthesize more selenolated nanoclusters with novel structures and properties. This review is based on publications available up to May 2019.
