Figure 2 Packing diagram of the title compound viewed along the c axis, showing the sheet-like structure in the ab plane. The dashed line indicates the π–π stacking interaction. Cg1 is the centroid of the pyrone ring. Symmetry codes: (vi) x, −y + $[{1\over 2}]$ , z − $[{1\over 2}]$ ; (vii) −x + $[{1\over 2}]$ , y, z − $[{1\over 2}]$ ; (viii) −x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z; (ix) −x, y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (x) x + $[{1\over 2}]$ , −y + 1, −z + $[{1\over 2}]$ ; (xi) −x, −y + 1, −z.
