Platinum(0)-platinum(0) dimers. Bonding relationships in a d10-d10 system

Synthesis, X-ray crystal structure, anti-fungal and anti-cancer activity of [Ag2(NH3)2(salH)2] (salH2=salicylic acid)

“…It has been speculated that such an attractive interaction between the Ag(I) d 10 cations is due to hybridisation of the metal 4d orbital with the higher energy 5s and 5p orbitals, which converts the closed-shell repulsion into a weak attractive interaction [11][12][13] 2 ] were screened for their ability to inhibit the growth of C. albicans (Table 2). Whilst metal-free salH 2 was essentially ineffective at controlling the growth of the organism, [Ag 2 (salH) 2 ] did show quite marked activity.…”

Electronic structures of solids from a simple viewpoint: some structures derived from the cesium chloride arrangement

“…Cu-Cu interaction increases by a small amount due to mixing of the metal d orbitals with higher-energy metal orbitals. Decreased Cu~-Cu ~ and Pt°-Pt ° distances in molecules with d I° metals have been ascribed to such effects (Mehrohta & Hoffmann, 1978;Dedieu & Hoffmann, 1978).…”

Aurophilicity: The Effect of the Neutral Ligand L on [{ClAuL}2] Systems

“…Existence of the effect: The empirical evidence for such an attraction between closed-shell (sub)systems was recognized for Ag I ···Ag I by Jansen, [9] for Au I ···Au I by Schmidbaur, [1,10] and, before them, for Pt···Pt [11] and Cu···Cu [12] by Hoffmanns group, who also suggested that a hybridization between the filled (nÀ1)d shells and the formally empty ns and np shells of the metal atoms could explain the structurally observed attraction. At the extended Hückel level, an attraction was, indeed, found.…”
