Piperidine-1-carboxamidinium ethyl carbonate.


ABSTRACT: In the title salt, C6H14N3(+)·C3H5O3(-), the C-N bond lengths in the central CN3 unit of the carboxamidinium cation are 1.3262?(18), 1.3359?(18) and 1.3498?(18)?Å, indicating partial double-bond character. The central C atom is bonded to the three N atoms in a nearly ideal trigonal-planar geometry and the positive charge is delocalized in the CN3 plane. The piperidine ring is in a chair conformation. The C-O bond lengths in the ethyl carbonate anion are characteristic for a delocalized double bond and a typical single bond. In the crystal, N-H?O hydrogen bonds between cations and anions generate a two-dimensional network in the direction of the ab plane, whereas adjacent ion pairs form chains running along the b axis.
