چکیده
The title compound, C25H24N3O3P, was obtained by catalytic phospho-nation of 4'-(4-bromphen-yl)-2,2':6',2''-terpyridine. The terpyridine moiety is nearly planar, the dihedral angles between the central and the outer rings being 4.06 (9) and 5.39 (9)°. The N atoms in the two pyridine rings are oriented nearly anti-periplanar to that of the central ring. The benzene ring is rotated out of the plane of the central ring of the terpyridine unit by 34.65 (6)°.
