2-(4-Fluorobenzylidene)propanedinitrile: monoclinic polymorph

Blog Article

The title compound, C10H5FN2, is a monoclinic (P21/c) polymorph of the previously click here reported triclinic (P-1) form [Antipin 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 fluorobenzene and dinitrile groups [C—C—C—C torsion roneverhart.com angle = 175.49 (16)°] is evident in the triclinic polymorph.In the crystal, C—H.N interactions lead to supramolecular layers parallel to (-101); these are connected by C—F.π interactions.
