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.

9-(4-Meth­oxy­phen­yl)anthracene

In the title compound, C21H16O, the dihedral angle between the anthracene ring system and the benzene ring is 74.3 (5)°. The anthracene ring system is essentially planar (r.m.s. deviation = 0.0257 Å) and the meth-oxy group lies in the plane of the benzene ring [C1-O1-C2-C7 torsion angle = 0.5 (2)°]. The crystal structure features π-π [centroid-centroid distance = 3.9487 (12) Å] and C-H⋯π inter-...

Ethyl anthracene-9-carboxyl­ate

In the title compound, C(17)H(14)O(2), the COO group and the anthracene fragment form a dihedral angle of 76.00 (19)°. The torsion angle around the O-Csp(3) bond of the ester group is 108.52 (18)°. The crystal structure is stabilized by C-H⋯O inter-actions and edge-to-face arene inter-actions with C-H⋯(ring centroid) distances in the range 2.75-2.84 Å.

9-(Pent-4-en­yl)anthracene

In the title compound, C(19)H(18), the anthracene system is almost planar, with a maximum deviation of -0.039 (1) Å. The structure is stabilized by C-H⋯π inter-actions. The pentene moiety is not planar and is twisted away from the attached anthracene system with a maximum torsion angle of 91.2 (1)°.

Tetra­kis(μ-anthracene-9-carboxyl­ato)bis­[(anthracene-9-carboxyl­ato)(2,2′-bipyrid­yl)lanthanum(III)]

The title complex, [La(2)(C(15)H(9)O(2))(6)(C(10)H(8)N(2))(2)], has a centrosymmetric binuclear cage structure in which two La(III )atoms are both nine-coordinated and bridged by four anthracene-9-carboxyl-ate ligands, with an La⋯La separation of 4.0880 (4) Å. The remaining coordination sites are occupied by two N atoms of a 2,2'-bipyridine (bipy) and two O atoms of an anthracene-9-carboxyl-ate...
