(Z)-2,2,2-Trichloro-N²-cyanoacetamidine

A. E. Baker and R. T. Boeré

Abstract: The title compound, C₃H₂Cl₃N₃, crystallizes as the Z isomer with respect to the C=N bond. The -C(NH₂)=NCN functional group is effectively planar (r.m.s. deviation = 0.016 Å), with only the three Cl atoms out of the molecular plane. A strong network of N-HN hydrogen bonds forms dimers which are associated into ribbons in the crystal structure. Hydrogen bonding is suspected to be the cause of the near-equivalence of the formal C-N and C=N bonds (_CN = 0.008 Å)
