Vibrational spectrum and structure of solid TlAu(CN)2

Crystal Structure, Electronic Structure, and Temperature-Dependent Raman Spectra of Tl[Ag(CN)2]: Evidence for Ligand-Unsupported Argentophilic Interactions

“…This is a large shift for salts of the same complex ion which differ only in the counter cation. A similar trend was noticed previously in the Raman data for Tl[Au(CN) 2 ] versus other M[Au(CN) 2 ] salts (M = K, Na, Li) . A possible explanation for the lower ν C - N frequencies in the thallium compounds is the electron density of thallium surrounding the cyanide groups (Figure ).…”

Hydrothermal synthesis, structural, Raman, and luminescence studies of Am[M(CN)2]3·3H2O and Nd[M(CN)2]3·3H2O (M=Ag, Au): Bimetallic coordination polymers containing both trans-plutonium and transition metal elements

“…As shown in Fig. 4a, the CN symmetric stretch for KAg(CN) 2 is observed at 2145 cm À1 , consistent with the previously reported value for this compound [49]. Upon coordination with Nd 3+ , the n CN band blue-shifts by $15 cm À1 and a single strong band appears at 2160 cm À1 .…”

Tunable Photoluminescence of Closed-Shell Heterobimetallic Au−Ag Dicyanide Layered Systems

“…Assignments of the Raman bands are given in Table . The Raman spectra of La[Ag x Au 1 - x (CN) 2 ] 3 , x = 0, 0.25, 0.50, 0.75, 0.90, and 1, systems can be conveniently discussed by analogy with the Raman spectra of KAu(CN) 2 and KAg(CN) 2 , which have been studied in detail. − In KAu(CN) 2 Raman studies, − bands are observed at ∼2160 cm -1 (CN stretch) and at ∼305 cm -1 (AuCN bend). In a previous work, the Au−C stretch has not been observed but has been assigned to be at 452 cm -1 , deduced from infrared combination bands.…”
