Crystal structure of {2,6-bis­[(di­methyl­amino)­meth­yl]phenyl-κ(3) N,C (1),N′}(bromido/chlorido)­mercury(II)

In the mol­ecular structure of the title compound, {2,6-bis­[(di­methyl­amino)­meth­yl]phenyl-κ(3) N,C (1),N′}[bromido/chlorido­(0.30/0.70)]mercury(II)–{2,6-bis­[(di­methyl­amino)­meth­yl]phenyl-κ(3) N,C (1),N′}[bromido/chlorido­(0.24/0.76)]mer­cury(II) (1/1), [HgBr(0.30)Cl(0.70)(C(12)H(19)N(2))]·[HgBr(0.24)Cl(0.76)(C(12)H(19)N(2))], there are two mol­ecules in the asymmetric unit of formula LHgX {L = 2,6-bis­[(di­methyl­amino)­meth­yl]phenyl and X = Cl/Br}. In each mol­ecule, the halide site is mixed Cl/Br, with occupancies of 0.699 (7):0.301 (7) and 0.763 (7):0.237 (7), respectively. The two mol­ecules are linked into dimers by a combination of Hg⋯Hg [Hg⋯Hg = 3.6153 (3) Å] and C—H⋯Cl and C—H⋯π inter­actions.
