5-(4-Chloro-phen-oxy)-6-isopropyl-3-phenyl-3H-1,2,3-triazolo[4,5-d]pyrimidin-7(6H)-one
Abstract:
In the title compound, C(19)H(16)ClN(5)O(2), the triazolopyrimidine ring system is essentially planar, with a maximum displacement of 0.021 (4) Å, and forms dihedral angles of 1.09 (9) and 87.74 (9)° with the phenyl and benzene rings, respectively. Short intra-molecular C-H⋯O and C-H⋯N hydrogen-bonding inter-actions occur within the molecule. In the crystal structure, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds into chains parallel to the b axis. In addition, π-π stacking inter-actions involving the triazole and pyrimidine rings of adjacent mol-ecules are observed, with centroid-centroid distances of 3.600 (3) Å.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...
