Abstract : An X-ray analysis of the molecular and crystal structure of 2-(4'-amino-5'-azamethenyl pyrimidyl)-3 pentene-4-ol was recently completed. Significant results of this work include the determination of the structural parameters of the pyrimidine ring with an accuracy hitherto unavailable in the chemical literature, and the elucidation of a comprehensive system of hydrogen bonds which, in large part, are responsible for the molecular packing as it exists in the crystal. Each molecule participates in a total of six hydrogen bonds. Two amino hydrogen atoms and one hydroxyl hydrogen atom participate in hydrogen bonds to other molecules and three nitrogen atoms (two in the ring and one in the long side-chain) participate in hydrogen bonds which have the hydrogen atom chemically bound to adjacent molecules.
