چکیده
The title compound, C(9)H(11)NO(2), was obtained as an unexpected product in an attempt to synthesize a triazene ligand. The title mol-ecule is almost planar, with the formamide and eth-oxy groups oriented at 2.7 (3) and 12.9 (2)°, respectively, with respect to the mean plane of the benzene ring. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, forming a chain along the a axis. Weak C-H⋯π inter-actions with an H⋯π distance of 2.78 Å reinforce the crystal packing, resulting in a three-dimensional network.

The title compound, C(17)H(14)N(2)O, crystallizes as a cis formamide isomer. The isoquinoline and benzene fragments are nearly perpendicular [dihedral angle = 81.79 (18)°], whereas the formamide group is virtually coplanar with the isoquinoline unit [dihedral angle = 1.66 (15)°]. Inter-molecular N-H⋯O hydrogen bonds link mol-ecules into a centrosymmetric dimer.

متن کاملInfrared spectrum of formamide in the solid phase.
Infrared spectra of solid formamide are reported as a function of temperature. Solid formamide samples were prepared at 30 K and then annealed to higher temperatures (300 K) with infrared transmission spectra being recorded over the entire temperature range. The NH(2) vibrations of the formamide molecule were found to be particularly very sensitive to temperature change. The IR spectra revealed...
