Abstract
The reaction of bis-(3-oxo-1,3-di-phenyl-prop-1-enolato-κ2 O,O')zinc(II), [Zn(dbm)2], with tris-[4-(pyridin-3-yl)phen-yl]amine (T3PyA) in tetra-hydro-furan (THF) afforded the title crystalline coordination polymer, {[Zn(C15H11O2)2(C33H24N4)]·C4H8O} n . The asymmetric unit contains two independent halves of Zn(dbm)2, one T3PyA and one THF. Each ZnII atom is located on an inversion centre and adopts an elongated octa-hedral coordination geometry, ligated by four O atoms of two dbm ligands in equatorial positions and by two N atoms of pyridine moieties from two different bridging T3PyA ligands in axial positions. The crystal packing shows a one-dimensional polymer chain in which the two pyridyl groups of the T3PyA ligand bridge two independent Zn atoms of Zn(dbm)2. In the crystal, the coordination polymer chains are linked via C-H⋯π inter-actions into a sheet structure parallel to (010). The sheets are cross-linked via further C-H⋯π inter-actions into a three-dimensional network. The solvate THF mol-ecule shows disorder over two sets of atomic sites having occupancies of 0.631 (7) and 0.369 (7).

Summary
The structure of coordination polymers generated from the self-assembly of metal ions and bridging organic ligands depends on the molecular structures of the ligands and the coordination geometries of the metal ions. The pyridyl-groupterminated spacer ligands with coordinating ability and optical or electronic functionalities have been widely used to construct a variety of coordination polymers with designable structures and attractive potential applications in material science (Robin & Fromm, 2006; Allendorf et al, 2009; Stavila et al, 2014). Triphenylamine-based structures are some of the most important moieties and electron-donating groups in organic electronic materials, e.g. organic or organic–inorganic hybrid light-emitting diodes and solar cells, because of their electroactivity, photoactivity and chemical stability (Shirota & Kageyama, 2007; Mahmood, 2016; Agarwala & Kabra, 2017). We report on the crystal structure of the title coordination polymer composed of an exo-tridentate tripyridyl-type ligand, a -diketonato ligand and a closed-shell ZnII atom as the building blocks.
