| Though the literature contains a huge number of publications on pyridine and its derivatives, no crystal structures of substituted N-amino pyridinium cations have been reported. The reaction of chloramine with 3,5-lutidine was carried out and formed to give the expected product. The product crystallized in the space group P1 bar with a = 7.663(1), b = 8.241(2), c = 8.266(2) A; and ;The 2,2-bis-(salicylideneamino)biphenyl ((sal);The reaction of 2-acetylpyridine succinic acid dihydrazone (apsh) with Cu(NO;More extensive structural studies on the metal complexes with an inorganic double helix are attractive in order to correlate the variability of the chemical, biological, and structural properties and to understand the self-assembling in supramolecular structures. |
