Supramolecular interactions in Cobalt(II)-nucleobases complexes: A methyl matter

Co(II)-thymine and uracil compounds with close structural resemblance at the molecular level, produce different supramolecular synthons that organize the crystal structure in different ways providing the opportunity to estimate the relative strength of the H-bonding supramolecular interactions. This information could be useful for the design of novel crystal architectures.56
