Abstract
The solvothermal reactions of Sr(NO3)2 with 1,4-benzenedicarboxylic acid (BDC) in a mixture of H2O/N,Nʹ-dimethylformamide (DMF) resulted in a novel coordination polymer, [Sr(BDC) (H2O)] (1), which was characterized by single crystal and variable temperature powder X-ray diffraction (VTPXRD), elemental analysis, infra-red (IR) spectroscopy, and thermogravimetric-mass spectrometric (TG-MS) analysis. Compound 1 crystallizes in the orthorhombic space group Pbca with a=1.1854(2) nm, b=0.7122 (1) nm, and c=2.0031(4) nm. It is a three-dimensional (3D) framework consisting of zigzag chains that are formed by face-shared SrO8 square antiprisms and bridging BDC ligands. TG-MS and VTPXRD studies revealed that the framework of compound 1 exhibited a high thermal stability.
