4. Conclusions
Four new binary and ternary gold(I) complexes are described, in
which the metal atoms are coordinated by thiosaccharinate anions
and by other ligands (PPh3, dppm and dppe). For two of them,
[Au(tsac)(PPh3)] and [Au2(tsac)2(dppm)]ꢀEtOH, the crystal struc-
tures had the expected typical structure for gold(I) thionates. The
theoretical optimization of the complexes yielded good agree-
ments between calculated and experimental geometries. The anal-
ysis performed corroborate that even if it is ‘‘ligand assisted’’ by the
bridge of the diphosphine molecule, an aurophilic interaction is
present in the [Au2(tsac)2(dppm)]ꢀEtOH complex.

DFT can reproduce metallophilic interactions reasonably well. In
our previous work [11], we have observed the existence of MOs
with high Ag–Ag bond character in the dinuclear [Ag2(tsac)2py]
complex using the DFT approach. Here, a similar study was per-
formed for [Au2(tsac)2(dppm)]. For [Au(tsac)(PPh3)] and [Au2(t-
sac)2(dppm)], the HOMOs (at ꢁ6.07 and ꢁ6.10 eV, respectively)

and the LUMOs (at ꢁ1.74 and ꢁ1.85 eV, respectively) are all of
p
character and localized over thiosaccharinate anions (Figs. 4
and 5). The HOMO and LUMO orbitals of [Au2(tsac)2(dppm)]
are localized over different thioamidic group. For the
[Au2(tsac)2(dppm)] complex all the MOs were analyzed, searching
those ones which present high contributions from Au atoms. Four
MOs have Au–Au bonding character, HOMO-30, HOMO-29, HOMO-
28 and HOMO-21 with high contributions of both metal centers.
