“…163 Moreover, Ag 3 [3,5-(CF 3 ) 2 Pz] 3 can also interact with oterphenyl (oTP)and thiophene-derivatives, forming supramolecular columns with a face-to-face stacking mode. 164,165 Recently, Omary's group reported a series of co-crystals consisting of M 3 [3,5-(CF 3 ) 2 Pz] 3 (M = Cu(I)/Ag(I)/Au(I)) and tetrathiafulvalene (TTF) derivatives. 166 TTF and its derivatives are well-known electron donors, while M 3 [3,5-(CF 3 ) 2 Pz] 3 species are electron-deficient.…”

Among the d 10 coinage metal complexes, cyclic trinuclear complexes (CTCs) or trinuclear metallocycles with intratrimer metal−metal interactions are fascinating and important metal−organic or organometallic π-acids/bases. Each CTC of characteristic planar or near-planar trimetal nine-membered rings consists of Au(I)/Ag(I)/Cu(I) cations that linearly coordinate with N and/or C atoms in ditopic anionic bridging ligands. Since the first discovery of Au(I) CTC in the 1970s, research of CTCs has involved several fundamental areas, including noncovalent and metallophilic interaction, excimer/exciplex, acid−base chemistry, metalloaromaticity, supramolecular assemblies, and host/guest chemistry. These allow CTCs to be embraced in a wide range of innovative potential applications that include chemical sensing, semiconducting, gas and liquid adsorption/separation, catalysis, full-color display, and solid-state lighting. This review aims to provide a historic and comprehensive summary on CTCs and their extension to higher nuclearity complexes and coordination polymers from the perspectives of synthesis, structure, theoretical insight, and potential applications.

“…28,36,37 Such luminescence, termed "metal-sensitized phosphorescence", is attributed to the enhanced intersystem crossing (ISC) rate from singlet excited states to triplet states mediated by external heavy-atom effect (e.g., Au, Ag, Cu and Hg). 38,39 In this way, we are proposing that the external isotropic pressure can enforce the interactions between CTCs and organic chromophores, resulting in alteration of electronic structures of emission center and triggering the PIPE. To our best of knowledge, the investigations of the luminescence behaviour of such organic chromophore-CTC adducts under high pressure have been rarely reported.…”

A new unsymmetrically substituted 2,2'-bipyridine ligand, 5-methyl-5'-carbomethoxy-2,2'-bipyridine (L) was isolated from the dry distillation of the copper(II) complex, monoaqua-bis(trans-5-methyl-pyridine-2-carboxylato-N,O)copper(II). The ligand was fully characterized. The spectroscopic and single-crystal X-ray diffraction (SCXRD) studies of the coordination compounds of the ligand with platinum(II) and silver(I); cis-Pt(L)Cl2 (1) and [Ag(L)2]PF6 (2), respectively are reported. In 1, the Pt centre coordinates to tertiary N atoms of the ligand and two chloride ions to form a neutral square-planar coordination sphere, while in 2, the Ag(I) centre is coordinated by two ligands through N atoms to generate a cationic flattened tetrahedron geometry in which two mean planes intersect each other at 50.93°. The pyridine rings are nearly coplanar as revealed by the torsion angle [N1-C5-C6-N3] of 0.32°. In both complexes, L acts as a chelating ligand through pyridyl N atoms. In 1, the molecular units are stacked in a head-to-tail fashion with a Pt•••Pt separation of 3.5 Å. Supramolecular self-assembly of the molecular units by extensive intermolecular contacts through C-H•••Cl and C-H•••O between the adjacent units results in an infinite two-dimensional flattened-out herringbone structure in the crystalline state. In 2, the molecular units are interconnected with each other by C-H•••O contacts between the adjacent units running parallel to each other. Both complexes are fluorescent in solution and have emission maxima in the UV-Vis regions, which is a very important property for optoelectronic applications. DFT (density functional theory) and TD-DFT (time-dependent-DFT) calculations were performed at B3LYP/6-311+G(d,p)/LANL2DZ level to explore structural, electronic, and spectroscopic properties to compare with the experimental results. The molecular orbitals (MOs) were carried out with DFT at the same level.
