Abstract:
In the title compound, C(24)H(27)N(2)P, the P atom is bonded to three C atoms in a trigonal-pyramidal geometry. The overall Ψ-trigonal-bipyramidal coordination of the P atom is established when the contribution of the electron lone pair and of the N-P donor-acceptor distance of 3.051 (3)Å are considered. The 4-methyl-piperazinyl ring adopts a chair conformation. Intra- and inter-molecular C-H⋯π hydrogen bonding leads to the consolidation of the structure.

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...
