说明

General description

Mercury(II) bromide (HgBr₂) affords 1:1 adducts on reaction with N,N,N′,N′- tetramethyl-o-phenylenediamine (o-Me₂N.C₆H₄.NMe₂). Single-crystal X-ray diffraction studies of these adducts have been reported.

Crystal Structures of the 1: 1 Adducts of N, N, N', N'-Tetramethyl-o-phenylenediamine with Zinc (II) Bromide and Mercury (II) Bromide and Iodide.

Methylmercury levels in predatory fish species marketed in Canada.

Don S Forsyth et al.

Food additives and contaminants, 21(9), 849-856 (2005-01-26)

Mercury was detected in all analysed samples of swordfish, marlin, shark and tuna purchased from major supermarket outlets and fish retailers in three cities across Canada. Total mercury and methylmercury levels ranged up to 3845 and 2346 ng g(-1), respectively.

Rapid reduction of Hg(II) by mercuric ion reductase does not require the conserved C-terminal cysteine pair using HgBr2 as the substrate.

S Engst et al.

Biochemistry, 37(33), 11496-11507 (1998-08-26)

Conditions are described under which the nonphysiological substrate mercuric bromide (HgBr2) is rapidly turned over, both by the wild type (CCCC) and by an active site double mutant (CCAA) of mercuric reductase in which the C-terminal cysteines 557' and 558'
