7-[4-(5,7-Dimethyl-1,8-naphthyridin-2-yl-oxy)phen-oxy]-2,4-dimethyl-1,8-naphthyridine methanol disolvate
Abstract:
The title compound, C(26)H(22)N(4)O(2)·2CH(3)OH, was synthesized and characterized by (1)H NMR spectroscopy and X-ray structure analysis. There is one half-mol-ecule in the asymmetric unit with a centre of symmetry located at the centre of the benzene ring. The two bridged naphthyridine ring systems are in an anti-parallel orientation. In the crystal structure, O-H⋯N, C-H⋯O and C-H⋯N inter-actions define the packing.

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.
