“…[70] It is noteworthy that the van der Waals radius of aC ua tom has been recently reexamined and it is approximately 1.96 . [71][72][73][74][75][76] As ar esult, cuprophilic interactions could be considered present based on aC u-Cu separation shortert han the sum of the van der Waals radii of two Cu atoms. It is thus evident that cuprophilic interactions are considerably weak and sometimes it is difficult to judge their existence, particularly when other secondary forces, such as hydrogen bonding, p-p stacking betweeno rganic groups, crystal packing effects etc.…”

Despite being weak attractive forces, closed‐shell metallophilic interactions play important roles in the Group 11 metal complexes on their diverse structural and physical features. A plethora of experimental and computational studies has thus been dedicated to such weak attractive d10–d10 interactions, particularly aurophilic and argentophilic interactions. Although d10–d10 CuI–CuI forces had been recognized for four decades, cuprophilic interactions are less explored and they are best evidenced by single‐crystal X‐ray crystallographic analysis on CuI complexes and aggregates thereof, by which precise information about the Cu⋅⋅⋅Cu contacts, shorter than the sum of two van der Waals radii (3.92 Å) between the copper centers concerned can be obtained. Based on recently compelling experimental and spectroscopic evidence for intra‐ and intermolecular cuprophilic interactions in copper chemistry, the present Minireview summarizes recent progress in the past three decades in the synthesis and structures of multinuclear homometallic copper complexes, whereby supported and unsupported d10–d10 CuI–CuI interactions are at work.

“…Distances between copper atoms of adjacent Cu 2 dumbbells ( d Cu–Cu = 319.7(2) pm) are slightly longer than the separation between layers in the structure (308.0(2) pm). Cu–Cu separations shorter than the sum of the van der Waals radii (approximately 392 pm) have been previously considered as cuprophilic d 10 –d 10 interactions. − The bonding characteristics between copper atoms were analyzed using the electron localization function (ELF), as shown in Figures and (right) and described below.…”

Tricopper Melaminate, a Metal–Organic Framework Containing Dehydrogenated Melamine and Cu–Cu Bonding

Crystals of Cu 3 (C 3 N 6 H 3 ) are formed by a solid-state reaction of CuCl with melamine to form a layered framework structure with open pores running along the hexagonal axis direction of the P6/mcc structure. The compound contains the hitherto unknown (C 3 N 6 H 3 ) 3− ion, assigned as melaminate. Bonding interactions within and between Cu−Cu dumbbells, which connect melaminate ions into layers, are analyzed by density functional theory calculations of the electron localization function and directional Young's modulus. Band structure calculations reveal the material to be a semiconductor with a band gap on the order of 2 eV.

“…However, CPs coordinated by low-valent soft metals with hard carboxylic acids are also important and show good prospects in luminescence and sensing fields. [19,20] [Cu3(L)2]2 was synthesized by Chakraborty et al and found to possess intense yellow emission and high lifetime, showing high performance for vapors including nitroaromatics. [21] Three novel silver-organic frameworks [Ag2(H2btec)(H2O)], [Ag3(Hbtec)] and [Ag4(btec)] reported by Xia et al exhibited excellent luminescence and high antibacterial activities.…”

Amphiphilic 4-(methylthio) benzoic acid (HMBA) combining soft methylthio and hard carboxylic groups was used to construct two isostructural coordination polymers of [Cu(MBA)]n (CP-1) and [Ag(MBA)]n (CP-2), and one complex of Cu2(MBA)4(CH3CN)2• CH3CN (3). This ditopic HMBA ligand realizes stable coordination of its carboxylic group with low-valent soft Cu + ion (in-situ reduction from Cu 2+ ) under the assistance of methylthio groups, forming CPs of CP-1 and CP-2. Meanwhile, based on the theory of hard and soft acid and base (HSAB), harder Cu 2+ ions (in-situ oxidation from Cu + ) only coordinate to carboxylic groups, affording a paddle-wheel dinuclear complex 3. These two CPs were also taken for luminescent researches in solid state. CP-1 exhibits single-peak emission at 540 nm while CP-2 emits both at 499 and 528 nm with green luminescence. The emissions of CP-1 and CP-2 are both attributed to 3 MLCT (triplet metal-to-ligand charge transfer) excitation state.
