چکیده
In the title mol-ecule, C(25)H(19)NO(2), the furyl ring is twisted by 46.3 (1)° with respect to the phenyl-ene ring bearing the amido group. In the stilbene unit, the two phenyl-ene rings (i.e. the rings connected through the -CH=CH- fragment) are twisted by 59.2 (1)°; in the biphenyl-ene unit, the two benzene rings are twisted by 35.5 (1)°. In the crystal structure, mol-ecules are linked by an N-H⋯O(amido) hydrogen bond into a zigzag chain running along the c axis.

The title compounds, C22H19F4NO4, (I), and C25H22F3NO5, (II), each contain a central nearly planar di-hydro-furan-one ring. The r.m.s. deviation from planarity of these rings is 0.015 Å in (I) and 0.027 Å in (II). The mol-ecules are T-shaped, with the major conformational difference being the O-C-C-O torsion angle [-178.9 (1) in (I) and 37.7 (2)° in (II)]. In the crystal of (I), mol-ecules are ...
متن کاملN,N′-(Biphenyl-2,2′-diyl)bis(furan-2-carboxamide)
The title mol-ecule, C(22)H(16)N(2)O(4), is a 2,2'-disubstituted biphenyl whose phenyl-ene rings are rotated by 66.5 (1)° so as to avoid repulsion by the substituents. Only one of the two amide -NH- fragments engages in hydrogen bonding, and this inter-acts with the amido -C(=O)- acceptor of an inversion-related mol-ecule to generate a hydrogen-bonded dimer.

In the title furan-carboxamide derivative, C11H8N2O4, the benzene and furan rings are rotated from the mean plane of the central fragment by 2.68 (5) and 7.03 (4)°, respectively. The nitro group forms a dihedral angle of 10.15 (5)° with the adjacent benzene ring. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions, forming helical chains running along [010].
