Crystal structure of 3-[2-(4-methylphenyl)ethynyl]-2H-chromen-2-one
The coumarin ring system in the title asymmetric alkyne, C(18)H(12)O(2), is approximately planar (r.m.s. deviation of the 11 non-H atoms = 0.048 Å), and is inclined with respect to the methylbenzene ring, forming a dihedral angle of 33.68 (4)°. In the crystal, supramolecular zigzag chains along th...
