Synopsis

Two molerides of 1-methyl-.i-fiuorouracil complex with one molecule of 9-ethyl-2,-6diaminopririne and c*rystalliae in a triclinic unit cell. The crystal striwtiire w&q solved by analysis af 3dimensional x-ray diffraction data. A sharpened Patternon map was wed to determine the stnirtiire with a psiiedo-heavy atom technique. The three molecules form a planar hydrogen bonded net. One of the pyrimidines forms a triple hgdrogen bonded Watson-Crick pair with the purine, while the other pyrimidine forms hydrogen bonds to adenine through the imidaxole nitrogen. The network is completed by purine-purine hydrogen bonds.
