| Popis: | The asymmetric unit of the title compound, [Zn2(C6H6O7)2(H2O)4]·C12H10N2·2H2O, comprises half of a centrosymmetric complex dimer, half of a 1,2-bis(pyridin-4-yl)ethene molecule, which lies across an inversion centre, and one lattice water molecule. Carboxylate groups of two dianionic citrate ligands bridge two ZnII ions to give the cyclic dimer, with each ZnII ion coordinated by four O atoms from the chelating citrate ligand (one hydroxy and three carboxylate, with one bridging) and two water O atoms, forming a distorted octahedral environment [Zn—O = 2.040 (3)–2.244 (3) Å]. In the crystal, O—H...O and O—H...N hydrogen bonds involving hydroxy groups and both coordinating and lattice water molecules link the dimers to give a three-dimensional framework structure. |
