Synthesis and crystal structure determination of the bicyclic [bis(μ-P,N-1-benzyl-2-imidazolyl-diphenylphosphine) (μ-O,O′-diperchlorate)dimercury(II)][diperchlorate]

Tenfold Metalation of Ferrocene: Synthesis, Structures, and Metallophilic Interactions in FeC10(HgX)10

“…So far, examples of strong Hg +II −Hg +II interactions are relatively rare [40–42] . Only a small number of crystal structures contain shorter contacts than the here reported 3.353(1) Å [36, 43–47] . Furthermore, only a few examples of crystal structures of permercurated compounds are known so far [48–50] …”

Mono and Tetranuclear Gold(I) Complexes of Tris(1-benzylimidazole-2-yl)phosphine

“…The new tertiary phosphine ligand is similar to poly(pyrazol-1-yl)borates . Previous investigations with the (1-benzylimidazole-2-yl)phosphine analogue, (Bzim)Ph 2 P, demonstrated that it can react at the P atom forming complexes such as (Bzim)Ph 2 PAuCl and [(Bzim)Ph 2 PMCl(cod)] (M = Rh(I), Ir(I)), or at P and N centers, as a bidentate ligand, forming dinuclear cationic complexes such as [μ-(Bzim)Ph 2 PM] 2 [X] 2 (M = Au(I), Ag(I); X = PF 6 ¯, BF 4 ¯, NO 3 ¯), [μ-(Bzim)Ph 2 PHgClO 4 ] 2 [ClO 4 ] 2 , and [{μ-(Bzim)Ph 2 PM(cod)} 2 ][BF 4 ] 2 (M = Rh(I), Ir(I)), or [(μ-(Bzim)Ph 2 P) 3 M 2 ][X] 2 (M = Ag(I), Cu(I); X = CF 3 SO 3 ¯, BF 4 ¯) . C−H bond activation of one of the phenyl rings of the (Bzim)Ph 2 P ligand was observed by adding [{Ir(μ-Cl)(cod)} 2 ] to [(Bzim)Ph 2 PIrCl(cod)] to give the hydride complex [IrCl(cod){μ-PPh(C 6 H 4 )-BzIm}IrHCl(cod)] .…”
