They are in simple shapes and bright colors.
O hydrogen bonds, forming a two-dimensional network.
O interactions help to form chains of molecules in the crystal structure.
The structure consists of chains running along the a axis. O hydrogen bonds and by short Cl. It is a glycoluril derivative with five fused rings. O interactions are found in the crystal structure.
O hydrogen bonds connect the diruthenium units into a chain. N hydrogen-bonding interactions contribute to the stability of the structure.
O intramolecular hydrogen bonds lead to the formation of a sequence of five-, six- and five-membered rings, respectively, which are edge-fused. The resulting two-dimensional network can be seen as a superimposed three-layer structure along the a axis.
N hydrogen bonds, leading to a chain structure. The conformers are linked by bifurcated three-centre hydrogen bonds, forming chains running along the a axis.
This is the key activity in the whole project. O hydrogen bonds that link adjacent molecules into one-dimensional extended chains.
A phenylethynyl-substituted benzene ring is fused to a seven-membered ring, which binds two of the N atoms from separate rings of the glycoluril system. The Cd atom lies on a center of inversion. The structure consists of chains running along the a axis. The triazole ring is almost coplanar with the pyrimidine ring. O hydrogen bonds to form layers.
