“…Further, the Ag•••Ag distance in this lattice (3.15 Å) shows an argentophilic interaction between Ag2 and Ag2′. 37 L1 is coordinated to its neighbors through a perchlorate ion along the c axis. The coordination of L1 and Ag along the a axis points to high interaction energy (high coordination) along this axis in comparison to the other.…”

“…We compared crystallographic planes shown in Figure , where a and c are lattice vectors (same as in bulk packing) and the corresponding lattice directions are indicated using arrows. Interestingly the crystal lattice shows that along the a axis two Ag ions (Ag2 and Ag2′) are coordinated to two neighboring L1 s. Further, the Ag···Ag distance in this lattice (3.15 Å) shows an argentophilic interaction between Ag2 and Ag2′ …”

Coordination-Controlled One-Dimensional Molecular Chains in Hexapodal Adenine–Silver Ultrathin Films

Growth of a silver coordination polymer of a C-symmetric hexaadenine ligand is studied on highly oriented pyrolytic graphite (HOPG), using high-resolution atomic force microscopy (AFM). This unusual ligand offers 6-fold multidentate coordination sites, and consequently, a multidimensional growth of coordination polymer is expected. Notably, each discrete hexapodal unit is bridged by two silver ions along one of the crystallographic directions, resulting in high interaction energy along this direction. When the polymer was deposited on an HOPG surface from a dilute solution, we observed abundant one-dimensional (1D) coordination polymer chains, with a minimum width of approximately 4.5 nm. The single-crystal structure using X-ray analysis is compared with the surface patterns to reconcile and understand the structure of the 1D polymer on an HOPG surface. The energy levels of Ag-L1 within the proposed model were calculated, on the basis of the X-ray crystal structure, and compared to the ligand states to gain information about the electronic structure of ligand upon Ag coordination. On the basis of the wave functions of a few molecular orbitals (MOs) near the Fermi energy, it is surmised that unfilled MOs may play a crucial role in the transport properties of the Ag-L1 adlayer.

The synthesis of heterobimetallic cluster with the Al-S-M (M = Cu and Ag) structural unit has been realized for the first time by the reaction of aluminum-dithiol LAl(SH)2 (L = HC[C(Me)N(Ar)]2, Ar = 2,6-iPr2C6H3) with (MesCu)4 and (MesAg)4 (Mes = 2,4,6-Me3C6H2), respectively. The isolated clusters exhibit core structures of Al2Cu4S4 and Al4Ag8S8, respectively. During the formation of the [LAl(SAg)2]4, a side product of LAlS6 is formed. However, the reaction of LAl(SH)2 with excess of sulfur and (MesAg)4 resulted in the formation of LAlS4 as the only product soluble in organic solvents. Both of them represent rare examples of aluminum polysulfides. All compounds were characterized by spectroscopic methods and single crystal X-ray diffraction studies.

“…The closed d 10 valence shell of silver(I) tolerates a variety of different coordination geometries. Simple silver(I) complexes can be either 2-coordinate and approximately linear or 3-or 4-coordinate, [3] but the use of chelating ligands often leads to polymeric species or multinuclear clusters.…”

An icosanuclear silver(I) cluster supported by bis(thiosemicarbazonato) ligands

2022

View full text Add to dashboard Cite

The synthesis and structural characterisation of an icosanuclear silver(I) cluster complex is reported here. The complex includes twenty silver(I) ions supported by eighteen bis(thiosemicarbazonato) ligands. The cluster of silver(I) ions involves several close Ag⋯Ag contacts suggesting some degree of argentophilic interactions and the bis(thiosemicarbazonato) ligands are present in three different conformations highlighting the ability of thiosemicarbazone ligands to coordinate to metal ions in different modes.
