2,4,5-Tris(pyridin-4-yl)-4,5-dihydro-1,3-oxazole.

ABSTRACT: 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.

Project description:In the title mol-ecule, C(12)H(15)NO(2), the oxazole ring adopts an envelope conformation. Overall, the mol-ecule is approximately planar, the dihedral angle between the mean plane through all but the methyl-ene C atom of the five-membered ring and the aromatic ring being 8.6?(1)°. A weak C-H?O inter-action contributes to the stabilization of the crystal structure.

2-(3-Methyl-2-nitro-phen-yl)-4,5-dihydro-1,3-oxazole.

Project description:In the title compound, C(10)H(10)N(2)O(3), an inter-mediate in the synthesis of anthranilamide insecticides, all the non-H atoms except the nitro-group O atom lie on a crystallographic mirror plane. The H atoms of the methyl group are disordered over two sets of sites with equal occupancies. In the crystal structure, C-H⋯N links lead to chains of mol-ecules propagating in [100].

Tetra-kis[μ-1,3-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene-κ(2)N:N']tris-ilver(I) tris-(hexa-fluoridophosphate).

Project description:In the title compound, [Ag(3)(C(12)H(12)N(2)O(2))(4)](PF(6))(3), one Ag(I) ion, lying on a twofold rotation axis, is coordinated by four N atoms from four 1,3-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in a distorted tetra-hedral geometry and the other Ag(I) ion is coordinated by two N atoms from two L ligands in a bent arrangement [N-Ag-N = 169.03 (17)°]. Two L ligands adopt a syn conformation, while the other two adopt an anti conformation. They bridge adjacent Ag(I) ions, forming a trinuclear complex. One of the PF(6) (-) anions is half-occupied, with the P atom located on a twofold rotation axis. The PF(6) (-) anions link the complex mol-ecules via Ag⋯F inter-actions [2.80 (2) and 2.85 (2) Å] into a polymeric chain along [100].

2-(4,5-Dihydro-1,3-oxazol-2-yl)quinoline.

Project description:The title compound, C(12)H(10)N(2)O, is approximately planar. The angle between the quinoline and 4,5-dihydro-oxazole ring systems is 11.91 (12)°. The mol-ecules pack into a herringbone array with no significant π-π inter-actions. The dihydro-oxazole N and O atoms are disordered over two positions, with almost equal site occupancy factors.

4,4-Dimethyl-2-[3-nitro-2-phenyl-1-(phenyl-sulfan-yl)prop-yl]-4,5-dihydro-1,3-oxazole.

Project description:In the title compound, C(20)H(22)N(2)O(3)S, the oxazoline ring is planar (r.m.s. deviation = 0.045?Å) and forms dihedral angles of 47.24?(8) and 10.11?(8)° with the S- and C-bound phenyl rings, respectively. The nitro group lies to the same side of the mol-ecule as the oxazoline ring but is orientated so as not to inter-act with the ring. Linear supra-molecular chains along [010] are formed via C-H?O and C-H?S contacts. Chains are consolidated into a three-dimensional architecture by C-H?? and van der Waals inter-actions.
