4,4′-Bipyridine–terephthalic acid (1/1)
The asymmetric unit of the title compound, C(10)H(8)N(2)·C(8)H(6)O(4), consists of one half-mol-ecule of each moiety, 4,4'-bipyridine (bpy) and terephthalic acid (bdc), both being located on crystallographic inversion centers. They are linked together via strong inter-molecular O-H⋯N hydrogen bonds, forming infinite chains propagating along [1-21]. The chains are further connected through C-H⋯O...
متن کاملTerephthalic acid–4,4′-bipyridine (2/1)
In the title compound, 2C(8)H(6)O(4)·C(10)H(8)N(2), the 4,4'-bipyridine mol-ecule is located on an inversion centre. In the crystal structure, strong inter-molecular O-H⋯N hydrogen bonds between the terephthalic acid and 4,4'-bipyridine mol-ecules lead to the formation of chains with graph-set motif C(2) (2)(8) along the diagonal of the bc plane.
متن کاملSyntheses and Co-Fluorescence of Complexes of Eu (III)/Gd (III) with Thienyltrifluoroacetonate, Terephthalic Acid and Phenanthroline
A series of complexes of europium (III)/gadolinium (III) with 2-thienyltrifluoroacetonate (HTTA), terephthalic acid (TPA) and phenanthroline (Phen) were synthesized by coprecipitation. The resulting complexes including Eu2(TPA)(TTA)4Phen2, Eu1.4Gd0.6(TPA)(TTA)4Phen2, Eu1.0Gd1.0(TPA)(TTA)4Phen2 and Eu0.8Gd1.2(TPA)(TTA)4Phen2 were characterized by elemental analysis, IR spectroscopy and thermal s...
متن کامل1,4-Bis(imidazol-1-yl)benzene–terephthalic acid (1/1)
In the title compound, C(12)H(10)N(4)·C(8)H(6)O(4), 1,4-bis-(imidazol-1-yl)benzene and terephthalic acid mol-ecules are joined via strong O-H⋯N hydrogen bonds to form infinite zigzag chains. Both mol-ecules are located on crystallographic inversion centers. The O-H⋯N hydrogen-bonded chains are assembled into two-dimensional layers through weak C-H⋯O and strong π-π stacking inter-actions [centro...
متن کاملSynthesis and Verification of Biobased Terephthalic Acid from Furfural
Exploiting biomass as an alternative to petrochemicals for the production of commodity plastics is vitally important if we are to become a more sustainable society. Here, we report a synthetic route for the production of terephthalic acid (TPA), the monomer of the widely used thermoplastic polymer poly(ethylene terephthalate) (PET), from the biomass-derived starting material furfural. Biobased ...
