Abstract: In the crystal structure of the title two-dimensional network, [HgCl2(C11H10N2O)]n, the asymmetric unit consists of HgCl2 dumbbells and one molecule of the quinazoline unit. Pseudo-octahedrally coordinated HgII cations are chloride-bridged via a crystallographic inversion centre leading to different Hg-Cl bonds (short and long) and linked by other Cl atoms via translation along the a axis. The quinazoline ligands connect the Hg-Cl-Hg-Cl chains by N and O atoms along the b axis, forming the two-dimensional network structure. The crystal structure is stabilized by weak non-classical C-HCl hydrogen bonds and aromatic - stacking interactions [centroid-centroid distances = 3.942 (4) and 3.621 (4) Å].
