The ZnII compounds, μ-4,4′-ethyl-enedibenzo-ato-bis- [acetato-aqua-(dipyrido[3,2-a:2′,3′-c]phenazine)zinc(II)] dihydrate, [Zn2(C2H3O2)2(C 16H10O4)(C18H10N 4)2(H2O)2]·2H2O, (I), and catena-poly[[[aqua-(pyrazino[2,3-f][1,10]phenanthroline)zinc(II)]-μ-4, 4′-ethyl-enedibenzo-ato] N,N-dimethyl-formamide hemisolvate], {[Zn(C 16H10O4)(C14H8N 4)(H2O)]·0.5C3H7NO} n, (II), display very different structures because of the influence of the N-donor chelating ligands. In (I), the coordination geometry of each ZnII centre is distorted octa-hedral, involving two N atoms from one dipyrido[3,2-a:2′,3′-c]phenazine (L1) ligand, and four O atoms from one bis-chelating acetate anion, one bridging 4,4′-ethyl-enedibenzo-ate (bpea) ligand and one water mol-ecule. Adjacent ZnII atoms are bridged by one bpea ligand to form a dinuclear complex, and the dinuclear species is centrosymmetric. Two types of π-π inter-actions between neighbouring dinuclear species have been found: one is between the L1 ligands, and the second is between the L1 and bpea ligands. In this way, an inter-esting two-dimensional supra-molecular layer is formed. The layers are further linked by O - H⋯O and O - H⋯N hydrogen bonds, generating a three-dimensional supra-molecular network. In (II), each ZnII atom is square-pyramidally coordinated by two N atoms from one pyrazino[2,3-f][1,10] phenanthroline ligand, three O atoms from two different bpea ligands and one water mol-ecule.
