3“…The hexanuclear polyoxomolybdate anions lie on centres of inversion. Each 2-(pyrimidin-2-ylamino)pyrimidinium cation forms an intramolecular N—H⋯N hydrogen bond and the cations are linked through self-complementary pairs of N—H⋯N hydrogen bonds into dimers across centres of inversion. …”

8“…The current repertoire of RNA-cleaving deoxyribozymes can cleave nearly all of the 16 possible dinucleotide junctions with rates of at least 0.1/min, with the exception of pyrimidine–pyrimidine (pyr–pyr) junctions, which are cleaved 1–3 orders of magnitude slower. …”
