Abstract:
The title compound, [Zn(C(8)H(7)O(2))(C(10)H(8)N(2))(2)](C(8)H(7)O(2))·C(8)H(8)O(2)·2H(2)O, is comprised of a Zn(2+) cation, two 2,2'-bipydine (bipy) ligands and one 3-methyl-benzoate anion (L(-)) together with one uncoordinating L(-) anion, one uncoordinating HL mol-ecule and two lattice water mol-ecules. The Zn(II) atom is coordinated by four N atoms of two bipy ligands and two O atoms from one L(-) ligand in a distorted octa-hedral geometry. Pairs of centrosymmetrically related complex mol-ecules form dimers via slipped π-stacking inter-actions between bipy ligands with an inter-planar distance of 3.470 (4) Å. The dimers are linked into supra-molecular chains along [111], via C-H⋯O hydrogen bonds. The uncoordinated L(-) anions, HL mol-ecules and water mol-ecules are connected with each other via O-H⋯O hydrogen bonds, forming chains between the metal complex chains and binding them together via C-H⋯O contacts. The resulting layers parallel to (010) are further assembled into a three-dimensional supra-molecular architecture through additional C-H⋯O inter-actions.

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...
