title: Dichloro[(6R,7S,8S,14S)-(-)-sparteine-kappa2N,N']mercury(II).
abstract: In the title compound, [HgCl2(C15H26N2)], the chiral alkaloid (6R,7S,8S,14S)-(-)-L-sparteine acts as a bidentate ligand, with two Cl- ligands occupying the remaining coordination sites, producing a distorted tetrahedron. The N-Hg-N plane is twisted by 81.1 (2) degrees from the Cl-Hg-Cl plane. The mid-point of the N...N line does not lie exactly on the Cl-Hg-Cl plane but is tilted towards one of the N atoms by 0.346 angstroms. Similarly, the mid-point of the Cl...Cl line is tilted toward one of the Cl atoms by 0.163 angstroms. The packing structure shows that the complex is stabilized by two interatomic Cl...H contacts involving both Cl atoms and the methylene or methine H atoms of the (-)-sparteine ligand.
