Terephthalic 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 کامل4,4′-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 کاملSelf-Assembled Microwires of Terephthalic Acid and Melamine
Self-assembled microwires of terephthalic acid (TPA) and melamine are prepared through the evaporation of water in a solution mixture of TPA and melamine. The microwires were characterized by using scanning electron microscope (SEM), attenuated total reflection infrared (ATR-IR) spectra, and cross-polarized optical microscopy (CPOM). The TPA•M microwires showed semi-conductive properties.
متن کامل5,5′-Dimethyl-2,2′-bipyridine
The asymmetric unit of the title compound, C(12)H(12)N(2), contains two half-mol-ecules related by an inversion center, the planes of their pyridine rings being oriented at a dihedral angle of 69.62 (4)°. In the crystal structure, a π-π contact between the pyridine rings [centroid-centroid distance = 3.895 (3) Å] may stabilize the structure. A weak C-H⋯π inter-action is also found.
متن کامل2,2′-Dimethyl-4,4′-bipyridine
In the crystal structure of the title compound, C(12)H(12)N(2), the mol-ecule is twisted around the central C-C bond, with a dihedral angle of 8.32 (5)° between the mean planes of the pyridyl rings. The crystal structure is stabilized by arene stacking inter-actions, with a distance of 3.81 (1) Å between the ring centroids.
