In the title compound, C(11)H(19)NO(4), the piperidine ring adopts a chair conformation. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, forming a layer parallel to the bc plane.
متن کاملOxalic acid–pyridine-4-carbonitrile (1/2)
In the title compound, 2C(6)H(4)N(2)·C(2)H(2)O(4), the oxalic acid mol-ecule lies about an inversion center. The pyridine ring of the pyridine-4-carbonitrile mol-ecule is almost planar, the largest deviation from the least-squares plane being 0.006 (1) Å; the nitrile N atom deviates from this plane by 0.114 (1) Å. In the crystal, the oxalic acid mol-ecules and the pyridine-4-carbonitrile mol-ec...
