N2 - The molecules of 2-amino-4,6-bis[N-methyl-N-(4- methylphenyl) amino]pyrimidine-5-carbaldehyde, C21H23N5O, (I), and 2-amino-4-(indolin-1-yl)-6-methoxypyrimidine-5-carbaldehyde, C14H14N4O2, (II), which crystallizes with Z' = 2 in the space group P (1) over bar, exhibit polarized electronic structures. Molecules of (I) are linked by a combination of N - H center dot center dot center dot O, C - H center dot center dot center dot O and C - H center dot center dot center dot pi(arene) hydrogen bonds into a three-dimensional framework structure, while those of (II) are linked into sheets by a combination of two N - H center dot center dot center dot O hydrogen bonds and one N - H center dot center dot center dot pi(arene) hydrogen bond.
