Crystal structure of (N1-benzyl-N1,N2,N2-trimethylethane-1,2-diamine-κ2N,N′)dichloridomercury(II)

Abstract

In the structure of the title compound, [HgCl2(C12H20N2)], the HgII 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 CH3 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].
