catena-Poly[[dichloridomercury(II)]-μ-1,4-bis-[(pyridin-2-yl)meth-oxy]benzene-κN:N']
Abstract:
In the title compound, [HgCl(2)(C(18)H(16)N(2)O(2))](n), the Hg(II) atom is four-coordinated in a distorted tetra-hedral environment defined by two Cl atoms and two N atoms from two 1,4-bis-(pyridin-2-ylmeth-oxy)benzene ligands. The ligand shows a non-coplanar conformation, in which the dihedral angles between the two terminal pyridine rings and the linking benzene ring are 7.275 (17) and 74.020 (14)°. The flexible ligands link the Hg(II) atoms into a chain running along [010], with an Hg⋯Hg separation of 10.335 (5) Å, which is equal to the b axis. The chains are connected by C-H⋯O and C-H⋯Cl hydrogen bonds.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
