IR spectra are plotted from anihdes of l-piperidine carbosylic acids CsH reN-(CHa),CONHCeHa-R in CHCla and CDCis solutions. In the cases of n =L and tz =4. weak intramolecular (NH ---N) hydrogen bonds are formed. An asymmetrical energy surface occurs and the proton is present at the N of the anilide

The 1:1 complex between the zwitterionic piperidinium-3-carboxylate (P3C) and salicylic acid (SAL), P3CÁSAL, has been characterized by single crystal X-ray analysis, FTIR and NMR spectroscopy, and by DFT calculations. The crystals are orthorhombic, space group Pbca, with a = 11.6477( 7), b = 9.1754(

A novel series of hydrogen-bonded solid 1 : 1 acid-base complexes of 15 N-labeled 2,4,6-trimethylpyridine (collidine) with carboxylic acids and their hydrogen bond deuterated analogs were synthesized and studied by 1 H magic angle spinning (MAS) and 15 N cross-polarization NMR with and without MAS.
