Poly[di-μ-chlorido-μ-(1,2,3,9-tetra­hydro­pyrrolo­[2,1-b]quinazolin-9-one-κ(2) N:O)-mercury(II)]

In the crystal structure of the title two-dimensional network, [HgCl(2)(C(11)H(10)N(2)O)](n), the asymmetric unit consists of HgCl(2) dumbbells and one mol­ecule of the quinazoline unit. Pseudo-octa­hedrally coordinated Hg(II) 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—H⋯Cl hydrogen bonds and aromatic π–π stacking inter­actions [centroid–centroid distances = 3.942 (4) and 3.621 (4) Å].
