“…In the presence of trace amounts of PdCl 4 2− , two shoulder peaks emerge at ≈336 and 610 cm −1 . The peak at 336 cm −1 is attributed to the ν 1 mode of FeCl 4 − with a tetra‐coordination configuration (Figure b), and is indicative of the transformation of FeCl x (H 2 O) 6− x into FeCl 4 − , whereas the peak at 610 cm −1 has not been reported in the literature. With the stepwise increase in the Pd/Fe ratio, the Raman bands at approximately 270, 535, and 800 cm −1 decrease, and the peak at 313 cm −1 , associated with PdCl 4 2− rather than PdCl 2 , becomes visible.…”

Precious metal intermetallic nanoclusters (IMNCs) are promising nanocatalysts for practical industrial applications. However, to date, the preparation of these nanoclusters has been restricted to harsh conditions, and only succeeds for a limited number of elements. This study developed a simple and efficient strategy that enables the synthesis of supported IMNCs under ambient conditions via inorganometallic coordination chemistry, specifically, by donating the Cl − ligand, a noble metal chloride (MCl a b− ) forms a heterobimetallic ion (M x Fe y Cl z n− ) with the coordination-unsaturated FeCl 3 . Upon reduction, the ordered heterobimetallic ions are simultaneously transformed into IMNCs and embedded into γ-Fe 2 O 3 nanosheets, which form from excess FeCl 3 . In addition to providing convincing spectral evidence for the structure of the heterobimetallic ions, magnetic measurements, atomicresolution electron microscopy, X-ray absorption spectroscopy, and Fourier transform infrared spectroscopy of chemisorbed CO collectively confirm the successful preparation of the L1 0 -phased Pd 3 Fe IMNCs. Furthermore, this versatile method can be extended to synthesize other IMNCs, such as AuFe and PtFe, and seems to be applicable to IrFe, RhFe, RuFe, and MCo. When utilized as a heterogeneous catalyst in a Heck coupling reaction, the prepared Pd 3 Fe IMNCs display satisfactory activity and stability, highlighting their potential applications as advantageous catalysts.
