Bis(4-hydroxymethyl-1,5-dimethylimidazole-N3)gold(I) chloride

Abstract

The complex, bis(1,5-dimethylimidazole-4-methanol-N3)gold(I) chloride, is a salt in which the ligand molecules are bound through N(3) atoms of the imidazole rings to the Au atom, which has an approximate inversion centre. Bond lengths and angles are normal.

Palladium Phosphino-Iminolate Complexes as Metalloligands for Coinage Metals: A Versatile, Ambivalent Behavior

“…The X-ray structure analysis revealed nearly identical bond distances within the two Pd moieties (Figure , Table ). The molecular structure of 8 ·BF 4 and in particular the Au−N bond lengths of 2.033(4) and 2.034(4) Å are comparable with those of complexes in which a gold center is coordinated, for example, by two pyrimidine moieties (av Au−N distance: 2.04 Å) 9 or two imidazole moieties (av Au−N distance: 2.01 Å) 4 ORTEP view of the structure of in 7 ·BF 4 with the atom-numbering scheme.…”

Solvent and counter ion effects in bis(imidazole) dinuclear heterometallacyclic complexes of gold(I): Some considerations of porosity

“…Conductance experiments by Dash and Schmidbaur [3] have indicated formation of a [AuL 2 ]-type ionic complex product in the substitution of the ligands in [AuCl(CO)] by imidazole. The first crystal structure determination of a related compound, bis [4-(hydroxymethyl)-1,5-dimethylimidazole-jN 3 ]gold(1+) chloride, indicates no interaction between the chloride and the gold centre [4]. Recently imidazoles comprising long alkyl chain substituents have been utilised in a study of metal-based liquid crystals and the formation of gold nanoplates [5].…”
