Anodic Formation of Ordered TiO

9-(Dimethoxy­meth­yl)anthracene

In the title compound, C(17)H(16)O(2), a dimethyl acetal of 9-anthraldehyde, the anthracene skeleton is planar and the two meth-oxy groups attached to the C atom at position 9 of the aromatic ring system are located above and below the ring system.

Anthracene-1,4,9,10-tetra­one

The asymmetric unit of the title compound, C14H6O4, contains three independent mol-ecules (A, B and C). In mol-ecule C, there are two disordered sets of two carbonyl O atoms [occupancies = 0.643 (11) and 0.357 (11)]. All three mol-ecules are non-planar due to repulsion between two O atoms in peri positions on the anthracene ring, showing a slight difference in deviation of the carbonyl O atoms....
