Abstract:
The salts [C6H11N2][AuCl4] (1) and [C8H15N2][AuCl4] (2) ([C6H11N2]+ ) 1-ethyl-3-methylimidazolium;
[C8H15N2]+) 1-butyl-3-methylimidazolium), prepared by a solvent-free method, display similar crystal structures.
1 crystallizes in the monoclinic P21/c space group (a ) 11.1915(15) Å, b ) 12.380(2) Å, c ) 9.2883(13) Å; â ) 98.810(16)°;
Z ) 4) and 2 in the triclinic P1h space group (a ) 7.9354(14) Å, b ) 8.3930(15) Å, c ) 11.397(2) Å; R )
83.94(2)°, â ) 87.93(2)°, γ ) 78.04(2)°; Z ) 2). In both cases, a unique motif is seen consisting of linear chains
of alternating corner-to-face arranged [AuCl4]- ions at Au‚‚‚Cl separations of 3.356(3) Å (1) and 3.452(3) Å (2).
Ionic liquid behavior is observed from 58 to 220 °C for 1 and 50 to 250 °C for 2.
