Crystal structure of the coordination polymer catena-poly[bis­­[hy­dr­oxy(phen­yl)acetato-κ2O1,O2]zinc(II)]-μ2-1,2-bis­­(pyridin-4-yl)ethane-κ2N:N′]

In the title polymeric ZnII compound, [Zn(C8H7O3)2(C12H12N2)]n, the Zn cation is coordinated by two N atoms from 1,2-bis­(pyridin-4-yl)ethane unit and four O atoms from two mandelate [or hy­droxy(phen­yl)acetate] anions in a slightly distorted octa­hedral coordination geometry. The 1,2-bis­(pyridin-4-yl)ethane unit bridges two ZnII cations, related by an inversion centre, to form a polymeric chain along [110]. The crystal structure features extensive O—H⋯O and weak C—H ⋯O hydrogen bonds, with C—H ⋯ π inter­actions and π–π inter­actions also being present. The centroid–centroid distance between the phenyl ring of the mandelate group and the 1,2-bis­(pyridine-4-yl)ethane moiety is 4.951 (2) Å. The 1,2-bis­(pyridin-4-yl)ethane ligand is disordered over two positions, with a refined occupancy of 0.578 (14) for the major component.
