N′-{2-[2-(4-Methoxyphenyl)ethenyl]phenyl}acetamide
In the title compound, C(17)H(17)NO(2), the phenyl-ene rings are nearly coplanar [dihedral angle 7.3 (1)°]. The acetamido group is twisted out of the plane of the aromatic ring in order to form an N-H⋯O hydrogen bond to the acetamido group of an adjacent mol-ecule, generating a helical chain running along the b axis.

In the title compound, C(8)H(7)N(3)O, there are two independent mol-ecules in the asymmetric unit, in which the angles between the pyridine ring and the isoxazole ring are 35.8 (6) and 10.6 (2)°. The crystal packing is stabilized by N-H⋯N hydrogen bonds, which result in the mol-ecules forming a two-dimensional supra-molecular layer.

The asymmetric unit of the title compound, C(12)H(12)N(2)O(3), contains two mol-ecules in which the benzene and isoxazole rings are almost coplanar, the dihedral angles between their mean planes being 1.76 (9) and 5.85 (8)°. The two mol-ecules inter-act with each other via N-H⋯N and N-H⋯O hydrogen bonds, which link the mol-ecules into layers parallel to the ac plane. The layers stack in a paral...

In the present investigation, a series of 3-(4-methoxyphenyl)-1-isonicotinoyl-5-(substituted phenyl)-formazans (5a-r) were synthesized by condensation of schiff base (3) and diazonium salt of various substituted aromatic amines, (3a-r). The intermediate schiff base (3) was itself synthesized by condensation of isonicotinic acid hydrazide with 4methoxybenzaldehyde (2). The structures of the comp...

The title compound, C(25)H(20)N(2)O(4), is a new spiro-isoxazoline derivative. It contains a five-membered isoxazoline ring (A), a tetra-lone unit (E and D), a 4-nitro-phenyl substituent (B), and a phenyl ring (C). The isoxazoline ring (A) has an envelope conformation, while the cyclo-hexenone ring (D) has an inter-mediate sofa/half-chair conformation. The aromatic ring of the 4-nitro-phenyl su...
