چکیده
In the title mononuclear complex, [HgI(2)(C(12)H(11)NO(3))], the Hg(II) ion has a distorted trigonal-planar coordination sphere defined by two I(-) anions and the N atom of a methyl 2-(quinolin-8-yl-oxy)acetate ligand. In the crystal, face-to-face π-π stacking inter-actions, with a centroid-centroid distance of 3.563 (9) Å, are observed.

In the neutral title complex, [HgCl(2)(C(12)H(11)NO(3))], the Hg(II) ion is penta-coordinated by two Cl atoms, one N atom and two weakly coordinating O atoms from the methyl 2-(quinolin-8-yl-oxy)acetate ligand. The coordination around the Hg(II) ion may be described as highly distorted trigonal-bipyramidal. Centrosymmetric dimers are formed by an additional weak Hg⋯Cl inter-action, leading to a...

In the title complex, [HgBr(2)(C(12)H(11)NO(3))], the Hg(II) ion has a distorted core trigonal-planar geometry comprising two Br atoms and one quinoline N atom of the methyl 2-(quinolin-8-yl-oxy)acetic acid ligand. The angles around the Hg atom vary from 100.31 (15) to 152.65 (4)°. Two additional Hg⋯O inter-actions [2.739 (1) and 2.905 (1) Å] complete the coordination sphere about the Hg(II) atom.
