“…The structure of 3 is one of seven distinct motifs observed in combination with the group (2,6-Me 2 C 6 H 3 NC)AuX (X = Cl, Br, I, CN, NO 3 or CCPh). 10, 17 In contrast, (Me 3 P)AuX (X = Cl, Br, O 2 CCF 3 , CN or NO 3 ) and (Bu t NC)AuX (X = Cl, Br, CN or NO 3 ) form two isostructural series based on the steric properties of the neutral ligand. 14 Crystals of (2,4,6-Me 3 C 6 H 2 NC)Au(SCN) 4 are also triclinic, space group P1 ¯, but with four formula units in the unit cell.…”

“…Many 4d and 5d isocyanide metal complexes (e.g., platinum, palladium, and gold; [1,2,4,[15][16][17][18][19][20][21][22][23][24][25]) have been reported, whereas the known 3d complexes are much less abundant. In particular, cationic (isocyanide)Cu I species are limited to [CuL 4Àn (CNR) n ] + (n = 1-4; L = ½ 2,2 0 -bipyridine, ½ 1,10-phenantroline, ½ dppe, ½ DAB, PPh 3 , pyridine; R = Me, t-Bu, Ph, Xyl, p-MeC 6 H 4 ) [26][27][28][29][30][31][32][33][34][35].…”

“…Variation of the R and X groups generates fascinating aggregates that include dimers, 1-dimensional extended-chain polymers, and 2-dimensional polymeric sheets. 8- 13 The photophysical behavior for the closely-related (OC)Au I Cl showed an intriguing luminescence with emission at 663 nm in the solid state, while the absorption in solution occurs at ca. 250 nm.…”

The preparation of three isonitrile complexes (p-tosyl)CH(2)NCAu(I)X (X = Cl, Br, and I) along with their structural, spectral, and computational characterization are reported. X-Ray crystallography reveals that these complexes all crystallize in the same space group, C2/c, and have closely related supramolecular structures. The three complexes exhibit crossed-dimer structures with short Au...Au aurophilic distances of 3.0634(4) A, 3.1044(7) A, and 3.1083(5) A, for X = Cl, Br, and I, respectively. These distances are among the shortest ligand-unassisted Au...Au interactions reported. While RNCAuX complexes that we reported earlier associate as anti-parallel, one-dimensional aurophilic polymers with long Au...Au distances (approximately 3.6 A) and exhibit orange-red phosphorescence, the analogous aurophilic dimers herein show seemingly counter-intuitive blue-green emissions despite having much shorter Au...Au distances. DFT computations are used to augment experiment and study the T(1) phosphorescent excited state of [RNCAuX](n) in parallel, anti-parallel, and staggered conformations. Excimeric bonding and large Stokes shifts are predicted for all models, the extent of which is sensitive to both "n" and conformation with trends commensurate with experimental luminescence data. Calculations for the three [MeNCAuX](2) dimeric complexes reveal blue-green phosphorescence with a red shift as a function of increasing halide softness, consistent with experimental data for (p-tosyl)CH(2)NCAu(I)X (Cl > Br > I). The overall experimental and theoretical work signifies the central role of ground-state aurophilic bonding and excited-state excimeric bonding on the electronic structure, hence facilitating development of structure-luminescence relations that may assist in the rational design of novel optoelectronic devices.
