Pg. Jones et B. Ahrens, GOLD(I) COMPLEXES WITH AMINE LIGANDS - 3 - COMPETITION BETWEEN AURIOPHILIC AND HYDROGEN-BONDING INTERACTIONS IN DIMERIC SPECIES, New journal of chemistry, 22(10), 1998, pp. 1041-1042
The gold(I) complexes (pip)(2)Au+Cl- and (Cy2NH)AuCl (pip = piperidine
, Cy = cyclohexyl) crystallise as loose dimers; in the ionic species N
-H ... Cl- hydrogen bonding is the main secondary interaction, whereas
in the neutral complex the N-H ... Cl hydrogen bonding is weaker but
is compensated by an auriophilic interaction.
