General Methods All reactions were performed under an atmosphere of argon in dried glassware, except when using
aqueous reagents. All chemicals were reagent grade and used as supplied unless stated otherwise.
Ligand 1a was prepared as previously reported by our group.[1] Reactions were magnetically stirred
unless stated otherwise. 1H NMR, 13C NMR and 19F NMR spectra were recorded on an Agilent DD2
600 spectrometer. Chemical shifts (δ) are reported in ppm relative to the residual solvent peak. The
multiplicities are reported as: s = singlet, d = doublet, t = triplet, q = quartet, sext = sextet, m =
multiplet, br = broad. Melting points were measured on a Büchi B540 melting point apparatus. IR
spectra were measured on a Perkin-Elmer Spectrum 100 FTIR spectrometer and reported in cm-1. The
intensities of the bands are reported as: w = weak, m = medium, s = strong. High-resolution mass
spectra (HR ESI and EI MS) and elemental analyses were performed by the MS service at the Organic
Chemistry Institute of the WWU Münster.

X-Ray Diffraction Data sets were collected with a D8 Venture Dual Source 100 CMOS diffractometer. Programs used:
data collection: APEX2 V2014.5-0 (Bruker AXS Inc., 2014); cell refinement: SAINT V8.34A (Bruker AXS
Inc., 2013); data reduction: SAINT V8.34A (Bruker AXS Inc., 2013); absorption correction, SADABS
V2014/2 (Bruker AXS Inc., 2014); structure solution SHELXT-2014 (Sheldrick, 2014); structure
refinement SHELXL-2014 (Sheldrick, 2014). R-values are given for observed reflections, and wR2
values are given for all reflections. R-values are given for observed reflections, and wR2 values are
given for all reflections.
X-Ray Crystal Structure Analysis of 2: A colorless needle-like specimen of C51H51Au3Cl3F3S3 2 x
CH2Cl2, approximate dimensions 0.029 mm x 0.065 mm x 0.305 mm, was used for the X-ray
crystallographic analysis. The X-ray intensity data were measured. A total of 1057 frames were
collected. The total exposure time was 13.21 hours. The frames were integrated with the Bruker
SAINT software package using a narrow-frame algorithm. The integration of the data using a
monoclinic unit cell yielded a total of 92891 reflections to a maximum θ angle of 25.35° (0.83 Å
resolution), of which 10066 were independent (average redundancy 9.228, completeness = 99.9%,
Rint = 12.88%, Rsig = 6.18%) and 9031 (89.72%) were greater than 2σ(F2). The final cell constants of a =
8.0568(5) Å, b = 14.4365(8) Å, c = 24.0039(16) Å, β = 99.640(3)°, volume = 2752.5(3) Å3, are based
upon the refinement of the XYZ-centroids of 9805 reflections above 20 σ(I) with 5.128° < 2θ < 52.81°.
Data were corrected for absorption effects using the multi-scan method (SADABS). The ratio of
minimum to maximum apparent transmission was 0.779. The calculated minimum and maximum
transmission coefficients (based on crystal size) are 0.1820 and 0.7910. The final anisotropic full-
matrix least-squares refinement on F2 with 622 variables converged at R1 = 3.92%, for the observed
data and wR2 = 6.78% for all data. The goodness-of-fit was 1.119. The largest peak in the final
difference electron density synthesis was 1.206 e-/Å3 and the largest hole was -1.661 e-/Å3 with an
RMS deviation of 0.198 e-/Å3. On the basis of the final model, the calculated density was 2.032 g/cm3
and F(000), 1608 e-.
X-Ray Crystal Structure Analysis of 3: A colorless prism-like specimen of C34H34Ag2F14S2Sb2,
approximate dimensions 0.132 mm x 0.226 mm x 0.285 mm, was used for the X-ray crystallographic
analysis. The X-ray intensity data were measured. A total of 1279 frames were collected. The total
exposure time was 7.43 hours. The frames were integrated with the Bruker SAINT software package
S3
using a narrow-frame algorithm. The integration of the data using an orthorhombic unit cell yielded a
total of 168450 reflections to a maximum θ angle of 26.37° (0.80 Å resolution), of which 7980 were
independent (average redundancy 21.109, completeness = 99.7%, Rint = 3.91%, Rsig = 1.22%) and 7915
(99.19%) were greater than 2σ(F2). The final cell constants of a = 17.4030(7) Å, b = 14.0758(6) Å, c =
15.9506(6) Å, volume = 3907.3(3) Å3, are based upon the refinement of the XYZ-centroids of 9626
reflections above 20 σ(I) with 5.332° < 2θ < 55.14°. Data were corrected for absorption effects using
the multi-scan method (SADABS). The ratio of minimum to maximum apparent transmission was
0.905. The calculated minimum and maximum transmission coefficients (based on crystal size) are
0.5300 and 0.7290. The final anisotropic full-matrix least-squares refinement on F2 with 487 variables
converged at R1 = 3.02%, for the observed data and wR2 = 7.56% for all data. The goodness-of-fit
was 1.210. The largest peak in the final difference electron density synthesis was 1.556 e-/Å3 and the
largest hole was -0.981 e-/Å3 with an RMS deviation of 0.132 e-/Å3. On the basis of the final model,
the calculated density was 2.094 g/cm3 and F(000), 2368 e-.

Computational Details Geometry optimizations of minima were carried out in the gas phase using Gaussian09[1] with the
b3lyp[2] functional and the LANL2DZ[3] pseudopotential for Au and Ag and the 6-311+G(d,p) basis set
for all other atoms. All optimized geometries were verified by frequency calculations as minima (zero
imaginary frequency). Entropic corrections to the free energies were calculated using Truhlar’s quasi-
harmonic approximation (vibrational frequencies lower than 100 cm-1 are set equal to 100 cm-1 to
correct for the breakdown of the harmonic oscillator approximation for low frequencies).[4]
GaussView 5.0[5] was used to generate input and visualize output structures. CYLview[6] was used to
render the computed structures.
