Abstract

The first methylamine complexes of gold are reported. Both crystallize in chiral trigonal space groups. In bis(methylamine)gold(I) chloride [(CH3NH2)2Au]+ Cl, the gold and chlorine atoms lie on twofold axes in space group P3121. The packing is largely determined by two hydrogen bonds of the form N–H···Cl, which combine to form chains of rings, the latter with graph set R42(12). Aurophilic interactions are at best borderline [Au···Au 3.9014(2) Å]. Cyano(methylamine)gold(I), (CH3NH2)AuCN crystallizes in space group P31; the molecules are connected by short aurophilic contacts [Au···Au 3.1507(2) Å] to form spiral chains parallel to the c axis, and also by two hydrogen bonds of the form N–H···N≡C.

Keywords: aurophilic interactions; gold; hydrogen bonds; methylamine
