The crystal structures of four di­meth­oxy­benzaldehyde isomers

The crystal structures of four di­meth­oxy­benzaldehyde (C(9)H(10)O(3)) isomers, namely the 2,3-, 2,4-, 2,5- and 3,5- isomers, are reported and compared to the previously reported crystal structures of 3,4-di­meth­oxy­benzaldehyde and 2,6-di­meth­oxy­benzaldehyde. All di­meth­oxy­benzaldehyde mol­ec...

description The crystal structures of four di­meth­oxy­benzaldehyde (C(9)H(10)O(3)) isomers, namely the 2,3-, 2,4-, 2,5- and 3,5- isomers, are reported and compared to the previously reported crystal structures of 3,4-di­meth­oxy­benzaldehyde and 2,6-di­meth­oxy­benzaldehyde. All di­meth­oxy­benzaldehyde mol­ecules in the crystal structures are nearly planar. The largest deviation (1.2 Å) from the aromatic plane is found for one of the meth­oxy groups of 2,3-di­meth­oxy­benzaldehyde. Upon rapid cooling of 3,4-di­meth­oxy­benzaldehyde and 3,5-di­meth­oxy­benzaldehyde, a metastable polymorph is formed. The crystal studied for the 3,5- isomer was refined as a two-component twin.
