چکیده
In the title compound, C11H6N2O {systematic name: 3-(prop-2-yn-1-yl-oxy)benzene-1,2-dicarbo-nitrile}, the 14 non-H atoms are approximately coplanar (r.m.s. deviation = 0.051 Å) with the terminal ethyne group being syn with the adjacent cyano residue. In the crystal, centrosymmetric dimers are connected by pairs of C-H⋯N inter-actions and these are linked into a supra-molecular tape parallel to (1-30) via C-H⋯N inter-actions involving the same N atom as acceptor.

In the title compound, C(11)H(6)N(2)O, the complete mol-ecule is generated by the application of crystallographic twofold symmetry (the mol-ecule is disordered about this axis). The prop-2-yn-1-yl residue is slightly twisted out of the plane of the benzene ring [C-O-C-C torsion angle = 173.1 (3)°] and is orientated away from the nitrile substituents. In the crystal, supra-molecular chains along...

The mol-ecule of the title chalcone derivative, C(21)H(20)O(5), consists of two substituted aromatic rings bridged by a prop-2-en-1-one group. The dihedral angle between the two benzene rings is 28.7 (7)°. In the crystal, mol-ecules are linked into C(10) chains running along the a axis by inter-molecular C-H⋯O hydrogen bonds, and the chains are cross-linked via C-H⋯π inter-actions.
