Crystal structure of (N (1)-benzyl-N (1),N (2),N (2)-tri­methyl­ethane-1,2-di­amine-κ(2) N,N′)di­chloridomercury(II)

In the structure of the title compound, [HgCl(2)(C(12)H(20)N(2))], the Hg(II) atom has a distorted tetra­hedral coordination sphere defined by two tertiary amine N-atom donors, as well as two Cl(−) anions [the dihedral angle between the N—Hg—N and Cl—Hg—Cl planes is 82.80 (9)°]. The five-membered chelate ring adopts an envelope conformation, with puckering parameters of Q(2) = 0.446 (6) Å and ϕ(2) = 88.8 (6)°, with the two amine CH(3) substituents on opposite sides of the ring. In the crystal, the mol­ecules are linked by C—H⋯Cl inter­actions into a zigzag chain parallel to [101].
