Zwitterionic 6-methyl-2-oxo-3-[1-(ureidoiminio)ethyl]-2H-pyran-4-olate monohydrate

“…The bond distances shown in Table 1 indicate that the C2-N3 iminium bond length of 1.303 (2) Å agree with similar bond in related compounds (Girija & Begum, 2004a;Girija et al, 2004b). This distance is slightly longer than a typical C=N bond (1.269 Å); but much shorter than the single carbon-nitrogen (1.409 Å) (Gowda et al 2007), because of the resonance.…”

4,4′-Methylenebis{N-[(E)-quinolin-2-ylmethylidene]aniline}

“…The corresponding bond lengths and bond angles are similar in both 4-methyl-N-[(E)-quinolin-2-ylmethylidene]aniline moieties. The N2-C10 imine (C=N) bond length of 1.270 (3) Å agrees with similar double bonds usually observed in related compounds (Girija et al, 2004), and it is much shorter than the N2-C11 single C-N bond of 1.425 (2) Å (Gowda et al, 2007).…”
