A new three-dimensional barium(II) coordination polymer con­structed from N,N′-bis­(glycin­yl)pyromellitic di­imide: microwave-assisted synthesis, structure, Hirshfeld surface analysis and properties

A new three-dimensional (3D) coordination polymer, namely, poly[di­aqua­[μ₅-2,2′-(1,3,5,7-tetra­oxo-1,2,3,5,6,7-hexa­hydro­pyrrolo­[3,4-f]iso­indole-2,6-di­yl)di­acetato]­barium(II)], [Ba(C₁₄H₆N₂O₈)(H₂O)₂]_n, (I), has been synthesized by the microwave-irradiated reaction of Ba(NO₃)₂ with N,N′-bis­(glycin­yl)pyromellitic di­imide {BGPD, namely, 2,2′-(1,3,5,7-tetra­oxo-1,2,3,5,6,7-hexa­hydro­pyrrolo­[3,4-f]iso­indole-2,6-di­yl)diacetatic acid, H₂L}. The title com­pound was structurally characterized by single-crystal X-ray diffraction analysis and powder X-ray diffraction analysis, as well as IR spectroscopy. In the crystal structure of (I), the Ba^II ion is nine-coordinated by six car­box­yl­ate O atoms from five symmetry-related L²⁻ dianions and one imide O atom, as well as two water O atoms. The coordination geometry of the central Ba^II ion can be described as a spherical capped square anti­prism. One car­box­yl­ate group of the ligand serves as a μ₃-bridge linking the Ba^II cations into a one-dimensional polynuclear secondary building unit (SBU). Another car­box­yl­ate group of the ligand acts as a μ₂-bridge connecting the 1D SBUs, thereby forming a two-dimensional (2D) SBU. The resulting 2D SBUs are extended into a 3D framework via the pyromellitic di­imide moiety of the ligand as a spacer. The 3D Ba framework can be simplified as a 5-connected hexa­gonal boron nitride net (bnn) topology. The inter­molecular inter­actions in the 3D framework were further investigated by Hirshfeld surface analysis and the results show that the prominent inter­actions are H...O (45.1%), Ba...O (11.1%) and C...H (11.1%), as well as H...H (11.1%) contacts. The thermal stability, photoluminescence properties and UV–Vis absorption spectra of (I) were also investigated. The coordination polymer exhibits a fluorescence emission with a quantum yield of 0.071 and high thermal stability.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
