The Crystal and Molecular Structure of Cyano(methylisocyanide)gold(I).

Structure Determination of Homoleptic AuI, AgI, and CuI Aryl/Alkylethynyl Coordination Polymers by X‐ray Powder Diffraction

“…The Cambridge Structural Database (CSD) survey on gold( I ) compounds reveals that the extended chains40 and sheet2b, 5h, 41 structures are known. However, our present two‐dimensional honeycomb network topology in 5 with significant Au⋅⋅⋅Au interactions is relatively uncommon and contrast to some polymeric examples of [{(CN)Au(CNMe)} ∞ ],41a [{(PhCC)Au(2,6‐(Ph 2 P)py)} ∞ ],5h [{(PhCC)Au(CNC 6 H 3 Me 2 –2,6)} ∞ ]2b and [(tpa) 2 Au][Au(CN) 2 ] (tpa=1,3,5‐triaza‐7‐phosphaadamantane)40g structures, which show linear arrays of weakly interacting Au I atoms.…”

The fascinating implications of new results in gold chemistry

“…atoms of the strictly linear molecules form puckered planes, from which the carbonyl and chloride ligands are pointing alternately up and down [27]. A similar situation is found in crystals of the complex H3CNCA-uCN with its linear chain of non-hydrogen atoms [28]. It is only for the methyl hydrogen atoms that the molecules are threefold symmetrical tops (point group C3,,, Figure 3).…”

“…The gold atoms are arranged in puckered sheets with short Au•••Au contacts[28]. Scheine of intermolecular interactions between linear two-coordinate gold(I) complexes X -Au-Y and their copper(I) and silver(I) counterparts.…”

Aminkomplexe des Goldes, Teil 7: Pseudosymmetrie bei Aminkomplexen des Gold(I)-cyanids [1] / Amine Complexes of Gold, Part 7: Pseudosymmetry in Amine Complexes of Gold(I) Cyanide

“…B. Triethylphosphan [3], Triphenylphosphan [4,5], Methylisocyanid [6] oder Imidazol-2-ylidenen [7] gefunden werden. Alle diese Komplexe weisen wegen der d 10 -Konfiguration von Gold(I) dië ubliche lineare Form L-Au-CN auf.…”
