5,5′-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.

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.

In the title compound, C(10)H(6)N(4)O(4), the pyridine rings are oriented at a dihedral angle of 67.8 (1)°. The O-atom pairs are trans, each displaced by a similar distance [average = 0.2331 (2) Å] out of the attached pyridine ring plane. In the crystal, inter-molecular C-H⋯O and C-H⋯N inter-actions link the mol-ecules into a three-dimensional network.
متن کامل2345 Parinaric acid a diagnostic technique for evaluation of lens membrane oxidation
Purpose: Lipid peroxidation has recently been associated to a number of agcrelated diseases including cataract development. This study was designed to establish the best conditions to adapt a technical approach based on the incorporation of a fluorescent pmbe (patina& acid) into biological membranes to monitor early stages of lipid pemxidation. The method allows both the evaluation of several f...
