Dinuclear organogold(i) complexes bearing uracil moieties: Chirality of Au(i)-Au(i) axis and self-assembly
The conjugation of dinuclear organogold(i) complexes with a bridging diphosphine ligand as an organometallic compound and the uracil derivative as a nucleobase was demonstrated to afford bioorganometallic conjugates. Single-crystal X-ray structure determination of the dinuclear organogold(i)-uracil conjugates revealed the assembly properties of gold(i) and the uracil moieties in the solid state. The crystal structure of (U6Au)2(mu-Xantphos) (U6 = 6-ethynyl-1-octyluracil) with Xantphos as the bridging diphosphine ligand revealed the presence of an intramolecular aurophilic Au(i)-Au(i) interaction. R- and S-enantiomers based on the Au(i)-Au(i) axis exist in the unit cell, which are connected alternately to form the hydrogen-bonded assembly through intermolecular hydrogen bonds between the uracil moieties. In the case of the dinuclear organogold(i) complex (U5Au)2(mu-Xantphos) (U5 = 5-ethynyl-1-octyluracil), both enantiomers were found to form homochiral RR and SS dimers, respectively, through pi-pi interactions between 5-ethynyl-uracil moieties. In the crystal packing, each dimer is assembled alternately to form the hydrogen-bonded assembly through intermolecular hydrogen bonds between the uracil moieties. As expected, the utilization of (R)-BINAP as a bridging diphosphine ligand with axial chirality induced the chirality of the Au(i)-Au(i) axis. The crystal structure of the dinuclear organogold(i) complex with (R)-BINAP (U6Au)2(mu-R-BINAP) confirmed the axial chirality of the Au(i)-Au(i) axis, forming a R,R-enantiomer, wherein each molecule is arranged through intermolecular hydrogen bonds between the uracil moieties to form a helical molecular arrangement.
