Abstract—µ-Oxo-bis[(4-methylbenzenesulfonato)triphenylantimony] (I) and µ-oxo-bis[(2,5-dimethylbenze-
nesulfonato)triphenylantimony] (II) were synthesized by reacting triphenylstibine Ph3Sb with tri-p-tolylbis-
muth bis(4-methylbenzenesulfonate) and tri-p-tolylbismuth bis(2,5-dimethylbenzenesulfonate), respectively, in
toluene in the presence of air moisture.According yo X-ray diffraction data, the antimony atoms in the compounds
synthesized have a distorted trigonal bipyramidal configuration. The SbOSb angles are equal to 138.5(2)° and
180°, respectively. A bent molecule I contains the Sb(1)···Sb(2) (3.690(1) Å) and Sb···S(1,2) (3.521(2),
3.559(2) Å) intramolecular contacts. In a linear molecule II, the Sb···S distances are equal to 3.438(1) Å.

were studied in this work.
(II)
The positions of the hydrogen atoms were determined
geometrically and refined in the rider model.
The data collection, processing and refinement of the
unit cell parameters were performed using the SMART
and SAINT-Plus programs [16]. All calculations for the
determination and refinement of the structure were per-
formed using the SHELXTL/PC program [17].
EXPERIMENTAL
Synthesis of I. A mixture containing 0.50 g of tri-p-
tolylbismuth bis(4-methylbenzenesulfonate) and 0.20 g
of triphenylstibine in 30 ml of toluene was kept in a
glass evacuated tube at 25°ë for 72 h. Large crystals
formed on the tube walls were collected, dried, and
weighted; 0.15 g (88%) of µ-oxo-bis[(4-methylbenze-
nesulfonato)triphenylantimony] was thus obtained (mp
215°C). The solvent was removed from mother liquor,
and the residue was recrystallized from water. The yield
was 0.30 g (94%); (mp 220°C).
Selected crystallographic data and the results of the
structure refinement are presented in Table 1, the coor-
dinates of atoms and their equivalent isotropic thermal
parameters are given in Table 2, and selected bond
lengths and angles are listed in Table 3.

RESULTS AND DISCUSSION
Triarylstibine is known to be oxidized with hydro-
gen peroxide in the presence of arenesulfonic acids to
yield µ-oxo-bis[(arenesulfonato)triarylantimony] [15].
We established that antimony compounds of this type
can be obtained in a high yield via the reaction of tri-
phenylstibine with tri-p-tolylbismuth bis(arene-
sulfonates) in ether in the presence of air moisture:
Synthesis of II. Complex II was synthesized simi-
larly, using the above-described procedure. The yield
was 87% (mp 220°C).
IR spectrum of II (ν, cm–1): 1270vs, 1150vs,
1100vs; 1060w; 1020s, 960vs.
X-ray diffraction analysis of complexes I and II
was performed on a Bruker SMART-1000 CCD diffrac-
tometer. For I, the data were collected in sets of 606,
435, and 230 scans at ϕ = 0°, 90°, and 180°, respec-
tively (ω scan mode with a step of 0.3° and 30 s per
frame). For II, sets of 909 scans were collected at

1.966(4) Å and coincide with analogous distances in
other bent structures [5], but they are longer than those
in complexes with linear structures [15]. In compound
II, the Sb–Obr distances are equal to 1.949(3) Å.
In µ-oxo-bis[(2-hydroxyethanesulfonato)triphenyl-
antimony], the SbOSb angle is equal to 180° [4], while
in (Ph3SbOSé2Ph)2O and (Ph3SbOSé2CF3)2O, analo-
gous angles are equal to 139.8° and 136.5°, respectively
[5]. The authors of [5] suggested that this difference in
SbOSb angles is due to the effect of crystal packing. In
complex I, the SbOSb angle (138.5°) slightly differs
from the latter two values, while in II, it is close to 180°.
The molecule of µ-oxo-bis[(2,5-dimethylbenzene-
sulfonato)tri-p-tolylantimony] also has linear structure
[15]. One can conclude that neither the electron-accept-
ing properties of arenesulfonate substituents nor the
methyl substituents in aryl ligands at the antimony
atom affect the SbOSb angle. The value of the SbOSb
angle seems to be affected not only by the crystal pack-
ing effect, but also by steric factors, namely, the size of
organic radical at the sulfur atom of the sulfonate frag-
ment. However, unambiguous conclusion cannot be
drawn on the basis of data available at present.
In bridged antimony compounds considered, the
bent geometry of molecules suggests that its fragments
approach one another such that they can interact and,
consequently, decrease the total energy of the system.
In this case, the nonvalent Sb···Sb interaction seems to
be most probable, particularly because coordinatively
unsaturated sphere of the Sb atom allows for its addi-
tional coordination [18]. Indeed, in compound I, the
Sb···Sb distance is equal to 3.690(1) Å that is less than
the twice van der Waals radius of antimony atom (4.40 Å)
but greater than its twice covalent radius (2.82 Å) [19].
This fact points to an interaction between the antimony
atoms in V-shape molecules of bridged antimony aryl
compounds. In the molecules of the complexes synthe-
sized, the intramolecular contacts were also observed:
Sb(1)···S(1) 3.521(2) Å, Sb(2)···S(2) 3.559(2) Å in I and
Sb···S 3.438(1) Å in II that are noticeably shorter than
the sum of the van der Waals radii of antimony and sul-
fur atoms (4.05 Å [19]). One can suggest that the
S···Sb···Sb···S interactions should ensure the saturation
of the coordination sphere of each Sb atom in complex I:

In linear molecule of complex II, the absence of contact
Sb···Sb is compensated by the sulfur atom of 2,5-dime-
thylbenzenesulfonate ligand approaching the antimony
atom (the Sb···S distance is equal to 3.438(1) Å).
