Poly[[[(1,10-phenanthroline-κ2N,N′)zinc(II)]-μ3-5-hydroxyisophthalato-κ4O,O′:O′′:O′′′] monohydrate]
Abstract
In the title compound, {[Zn(C8H4O5)(C12H8N2)]·H2O}n or {[Zn(OH-BDC)(phen)]·H2O}n (where OH-H2BDC is 5-hydroxyisophthalic acid and phen is 1,10-phenanthroline), the Zn atoms are coordinated by two N atoms from the phen ligands and by four O atoms from hydroxyisophthalate ligands in a highly distorted octahedral geometry, with Zn—O distances in the range 2.042 (4)–2.085 (5) Å and Zn—N distances of 2.133 (5) and 2.137 (5) Å. The {[Zn(OH-BDC)(phen)]·H2O}n infinite zigzag polymer forms a helical chain of [Zn2(OH-BDC)2]n units. Face-to-face π–π interactions (3.60–3.75 Å) occur between two phen rings belonging to the same helical chain. Consolidation of the packing structure is achieved by O—H⋯O hydrogen-bonding interactions between the carboxylate O atoms, the hydroxyl group and the water molecule, forming two-dimensional sheets.
