Figure 1 The mol­ecular structure of the title compound. For clarity, two symmetrically independent mol­ecules are shown separately (a and b) with hydrogen atoms omitted. Carbon atoms of the chroman systems which adopt two different conformations, are shown in green and blue, respectively. Displacement ellipsoids are drawn at the 50% probability level.
