Crystal structure of (N (1)-benzyl-N (1),N (2),N (2)-tri-methyl-ethane-1,2-di-amine-κ(2) N,N')di-chloridomercury(II).

In the structure of the title compound, [HgCl2(C12H20N2)], the Hg(II) atom has a distorted tetra-hedral 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 CH3 substituents on opposite sides of the ring. In the crystal, the mol-ecules are linked by C-H⋯Cl inter-actions into a zigzag chain parallel to [101].
