New neutral gold(III) complexes having formulae AuX3(pyiuPr) and AuX3(pyiuCy) were synthesized and characterized (X = Cl, Br; pyiuPr = 1,3-diisopropyl-2-((pyridin-2-yl)methyl)isourea; pyiuCy = 1,3-dicyclohexyl- 2-((pyridin-2-yl)methyl)isourea). The N-donor ligands coordinate the metal centre through only one nitrogen atom and DFT calculations support the formation of Au-N(pyridine) bonds. Variable-temperature NMR experiments suggest the formation of intermolecular hydrogen bonds among isourea moieties in CDCl3 solution

Abstract
New neutral gold(III) complexes having formulae AuX3(pyiuPr) and AuX3(pyiuCy) were synthesized and characterized (X = Cl, Br; pyiuPr = 1,3-diisopropyl-2-((pyridin-2-yl)methyl)isourea; pyiuCy = 1,3-dicyclohexyl- 2-((pyridin-2-yl)methyl)isourea). The N-donor ligands coordinate the metal centre through only one nitrogen atom and DFT calculations support the formation of Au-N(pyridine) bonds. Variable-temperature NMR experiments suggest the formation of intermolecular hydrogen bonds among isourea moieties in CDCl3 solution
