2,4,5-Tris(pyridin-4-yl)-4,5-dihydro-1,3-oxazole.
In the title compound, C(18)H(14)N(4)O, the mol-ecules are disordered about a crystallographic twofold axis, leading to 50:50 disorder of the O- and N-atom sites within the oxazole ring. As a consequence, symmetry-related oxazole C-N and C-O bonds are averaged. The oxazole ring makes a dihedral angle of 6.920 (1)° with the pyridyl ring in the 2-position and 60.960 (2)° with the pyridyl rings in the 4- and 5-positions.
