Key indicatorsSingle-crystal X-ray study T = 293 K Mean '(C±C) = 0.002 A Ê R factor = 0.043 wR factor = 0.117 Data-to-parameter ratio = 14.8For details of how these key indicators were automatically derived from the article, see A view of (I), with the atom-numbering scheme and 50% probability displacement ellipsoids.

4-(2-Bromo-4,5-dimethoxybenzyloxy)phthalonitrile

“…1. The lengths of the two C N triple bonds (Table 1) are consistent with those found in similar compounds (Atalay et al, 2003;Erdem et al, 2004;Ískeleli & Ag ar, 2005). The C-Br bond distance is close to the values reported for 4-(3-bromobenzylideneamino)-3-(4-chlorobenzyl)-4,5-dihydro-1H-1,2,4triazol-5-one .…”

4-(2-Formylphenoxy)phthalonitrile

“…The molecule of the title compound, (I) is not planar: the dihedral angle between the phthalonitrile moiety and the 2formylphenoxy group is 62.68 (4) . The lengths of the two N C triple bonds [C1 N1 = 1.3333 (17) Å and C2 N2 = 1.1409 (17) Å ] are consistent with those found in similar compounds (Ocak et al, 2003(Ocak et al, , 2004Atalay et al, 2003;Erdem et al, 2004).…”

4-(3,4-Methylenedioxyphenoxy)phthalonitrile

“…The CÐO and CÐC bond distances in the 3,4-methylenedioxyphenoxy group are similar to values reported in the literature (Okamoto et al, 1993. The lengths of the two C N triple bonds [C1 N1 = 1.140 (2) A Ê and C2 N2 = 1.143 (2) A Ê ] are consistent with those found in similar compounds (Ocak et al, 2003(Ocak et al, , 2004Atalay et al, 2003;Erdem et al, 2004). In the crystal structure, the molecules are stacked in the a-axis direction and are connected via weak intermolecular CÐ HÁ Á ÁN contacts into chains, which extend in the c-axis direction.…”
