Preparation and crystal structure of tetramercury bis(hexafluoroarsenate) Hg4(AsF6)2

Mercury Phosphates with the Triangular Hg4+3 Cluster: (Hg3)3(PO4)4 and (Hg3)2(HgO2)(PO4)2

“…[4]), like the di!erent mercury cations among each other (Eq. [5]). Exceeding of the solubility product during decrease of temperature leads to the crystallization of the complex salts -(Hg ) (PO ) , (Hg ) (PO ) , and (Hg ) (HgO )(PO ) (Eq.…”

The Reactivity of [Zn2Cp*2]: Trapping Monovalent {.ZnZnCp*} in the Metal‐Rich Compounds [(Pd,Pt)(GaCp*)a(ZnCp*)4−a(ZnZnCp*)4−a] (a=0, 2)

“…[24,25] In comparison, compound 2 is among the very few examples [26] of molecular compounds featuring oligo (hetero) metal chains without stabilization of the internal chain atoms by ligands, similar to the ligand-free, infinite metal chains in some solid state compounds, for example, Hg 3 (AsF 6 ) 2 and Hg 4 (AsF 6 ) 2 ). [27,28] Notably, treatment of [(Pd,Pt)(GaCp*) 4 ] with a large excess of [Zn 2 Cp* 2 ] does not lead to products with a (Ga + Zn)/(Pd,Pt) coordination number of more than eight. For example, icosahedral homoleptic molecular compounds [(Pd,Pt)(ZnR) 12 ] exhibiting (Pd,Pt)Zn 12 cores known from intermetallic (Pd,Pt)/Zn phases [29,30] and being similar to the MoZn 12 core of [Mo(ZnCp*) 3 (ZnMe) 12 ] turn out to be notoriously inaccessible.…”

Synthesis and crystal structures of HgFAsF6, Hg(HF)2(AsF6)2, Hg(HF)(AsF6)2 and Hg(AsF6)(SO3F)

“…Although the X-ray diffraction patterns of the products of the reactions: (a) Hg(AsF 6 ) 2 /Hg(SO 3 F) 2 (1:1) in liquid aHF, (b) HgFAsF 6 /S 2 O 6 F 2 , (c) Hg 2 (AsF 6 ) 2 /S 2 O 6 F 2 , (d) Hg(AsF 6 ) 2 /Hg(SO 3 F) 2 (1:1) in BrF 5 , and (e) HgF(AsF 6 )/HSO 3 F (1:1) indicate the presence of Hg(AsF 6 )(SO 3 F) their Raman spectra show that these products are mixtures of various phases. Since reaction between HgFAsF 6 and HSO 3 F yields Hg(SO 3 F) 2 (Table S1) one of the options would be to try reaction between HgFSO 3 F and AsF 5 , however first is necessary to find the way to prepare HgFSO 3 F which it is unknown.…”

“…The oxidation of mercury with AsF 5 using SO 2 as a solvent yields various homopolyatomic cations of mercury stabilized by [AsF 6 ] À anions [1,2]. The formal oxidation state of mercury in those compounds is lower than þ2 which is otherwise typical of Group 12 elements.…”

“…The formal oxidation state of mercury in those compounds is lower than þ2 which is otherwise typical of Group 12 elements. The large excess of AsF 5 yields Hg 2 2 þ salt, meanwhile with the decreasing amount of the oxidant, Hg 3 2 þ , Hg 4 2 þ and Hg 2.86 þ compounds can be prepared [1][2][3]. Later it was discovered that the reaction of mercury with various Hg(II) hexafluorides, Hg(MF 6 ) 2 (M ¼As, Sb, Nb, Ta), is a more useful and more general method of preparing Hg 3 2 þ and Hg 4 2 þ salts [1,2].…”
