Double complex salts [Pd(NH3)4]3[Rh(NO2)6]2, [Pd(NH3)4]3[Rh(NO2)6]2·H2O as promising precursors to prepare Pd-Rh nanoalloys

Crystal structures of [Pd(NH3)3(NO2)][Rh(NH3)2(NO2)4] and [PdEn2][Rh(NH3)(NO2)5]·0.75H2O

“…In [9], for the corresponding anion, the following values were obtained: Pd-N(NO 2 ) 1.984 Å, Pd-N(NH 3 ) 2.034-2.053 Å; in the neutral trans-[Pd(NH 3 ) 3 (NO 2 )] complex, the lengths of these bonds are 2.010 Å and 2.045 Å [23] respectively. The same relation could be observed when comparing the characteristics of tetranitrite and tetrammine cations [see, e.g., 6,7,24,25]. The palladium atom is by 0.019 Å out of the plane of coordinating it nitrogen atoms; in [9], this value was 0.…”

Synthesis, crystal structures, and characterization of double complex salts [Au(en)2][Rh(NO2)6]·2H2O and [Au(en)2][Rh(NO2)6]

“…Bond angles NeRheN are close to the ideal value of 90 : deviations are within 1.5 for 1 and 0.8 for 2. The average distance RheN is 2.048 Å in 1 and 2.046 Å in 2 being close to the values reported for hexanitrocomplexes of rhodium, e.g., [Co(NH 3 ) 6 ][Rh(NO 2 ) 6 ] [16], [Pd(NH 3 ) 4 ] 3 [Rh(NO 2 ) 6 ] 2[17]. In the nitro groups of the complex anions the lengths of the bonds NeO show little variation (1.227e1.252, av.…”

Bimetallic Pt–Re Nanoporous Networks: Synthesis, Characterization, and Catalytic Reactivity

“…Thus, this approach ensures that the elemental ratio in the alloy is precisely predetermined. Initial studies have demonstrated that various BNNs, such as Ag–Au, Fe–Pt, and Pd–Rh, can be prepared by this synthetic approach. ,,, …”
