Morpholine-4-carboxamidinium ethyl carbonate

چکیده

The asymmetric unit of the title salt, C5H12N3O(+)·C3H5O3(-), contains two carboxamidinium and two ethyl carbonate ions. In the crystal, the C-N bond lengths in the central CN3 units of the cations range between 1.324 (2) and 1.352 (2) Å, indicating partial double-bond character. The central C atoms are bonded to the three N atoms in a nearly ideal trigonal-planar geometry and the positive charges are delocalized in the CN3 planes. The morpholine rings are in chair conformations. The C-O bond lengths in both ethyl carbonate ions are characteristic for delocalized double bonds [1.243 (2)-1.251 (2) Å] and typical single bonds [1.368 (2) and 1.375 (2) Å]. In the crystal, N-H⋯O hydrogen bonds between cations and anions generate a two-dimensional network in the ac plane.

In the title compound, C(23)H(34)N(4)O(4), the morpholine rings adopt chair conformations. The N atom of the indol-2-one group is linked to the N atom of one morpholine ring through a flexible ethyl group with an almost cif conformation. In the crystal, molecules are linked by C-H⋯O interactions into infinite chains along the c direction. The almost parallel infinite chains are further inter-co...

The title compound, C(9)H(10)N(2)O(2)S, was obtained from the treatment of ethyl 4-cyano-3-hydr-oxy-5-morpholinothio-phene-2-carboxyl-ate with concentrated HCl. The mean plane of the essentially planar dihydro-thio-phene ring is almost orthogonal to the mirror plane of the N-morpholine substituent, making a dihedral angle of 87.2 (2)°.
