A triclinic polymorph of (E)-2-(2-nitroethenyl)furan

چکیده
The title compound, C(6)H(5)NO(3), crystallizes in the triclinic system with six independent mol-ecules in the asymmetric unit. In a previous study, the structure of the title compound was determined in the monoclinic P2(1)/n space group at 100 K [Valerga et al. (2009 ▶). Acta Cryst. E65, o1979]. All six independent mol-ecules display an E configuration about the C=C double bond, with the dihedral angles between the planes of the furan rings and the nitro-alkenyl groups ranging from 0.61 (7) to 5.03 (7)°. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen-bonding inter-actions.

The title compound, C(6)H(5)NO(3), was synthesized via condensation of furfural with nitro-methane in the presence of isobutyl-amine. The compound crystallizes exclusively as the E isomer. The angle between the mean planes of the furan ring and the nitro-alkenyl group is 1.3 (2)°.

The title compound, C18H18O4, is a triclinic polymorph of the previously reported monoclinic polymorph [Han & Zhen (2005 ▶). Acta Cryst. E61, o4358-o4359]. In the crystal of the triclinic polymorph, molecules are linked by two pairs of C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (102), and enclosing loops with graph set motifs of R2(2)(8) and R2(2)(6).

The asymmetric unit of the triclinic polymorph of the title compound, C21H25N3O3, consists of two mol-ecules, whereas for the monoclinic polymorph Z' = 1 [Fun et al. (2009 ▶). Acta Cryst. E65, o445]. The two mol-ecules exhibit an E configuration with respect to the C=N bond. The mol-ecules are linked into dimers by N-H⋯O and C-H⋯O hydrogen bonds forming R 2 (2)(8) ring motifs. In addition, π-π ...

The asymmetric unit of the title compound, C(10)H(6)N(4)O(4)S(2), contains two independent but similar mol-ecules. The structure is a triclinic polymorph of the monoclinic structure reported previously [Brito, Mundaca, Cárdenas, López-Rodríguez & Vargas (2007 ▶). Acta Cryst. E63, o3351-o3352]. The most obvious difference between the two polymorphs is the C-S-S-C torsion angle [-80.13 (16), -79....

The title compound, C10H5FN2, is a monoclinic (P21/c) polymorph of the previously reported triclinic (P-1) form [Anti-pin et al. (2003 ▶). J. Mol. Struct. 650, 1-20]. The 13 non-H atoms in the title polymorph are almost coplanar (r.m.s. deviation = 0.020 Å); a small twist between the fluoro-benzene and dinitrile groups [C-C-C-C torsion angle = 175.49 (16)°] is evident in the triclinic polymorph...
