Poly[di-?-chlorido-?-(1,2,3,9-tetra-hydro-pyrrolo-[2,1-b]quinazolin-9-one-?N:O)-mercury(II)].


ABSTRACT: 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 mol-ecule of the quinazoline unit. Pseudo-octa-hedrally 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 ?-? stacking inter-actions [centroid-centroid distances = 3.942?(4) and 3.621?(4)?Å].
