Crystal structure of 4-oxo-4H-chromene-3-carboxylic acid
In the title compound, C(10)H(6)O(4), also known as 3-carboxychromone, the non-H atoms of the chromone ring are essentially coplanar (r.m.s. deviation = 0.0057 Å), with the maximum deviation from their least-squares plane [0.011 (2) Å] being for a pyran C atom. The dihedral angle between the fused...
