The title compound of N,N′-bis(3,5-dichlorophenyl)formamidine, which is abbreviated as H(3,5-Cl2-pf), was isolated, and the crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. It crystallizes in the triclinic space group P1 with a = 7.9265(13)Å, b = 9.3588(15)Å, c = 10.4003(17)Å, α = 76.579(3)°, β = 72.529(2)°, γ = 74.249(2)°, V = 698.7(2)Å3, Dx = 1.588 g/cm3, and Z = 2. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0276 and 0.0771, respectively, for all 3046 independent reflections. The C-N (amine) single bond (1.3486(18)Å) and C=N (imine) double bond (1.2836(18)Å) within the H(3,5-Cl2-pf) molecule were confirmed. Two H(3,5-Cl2-pf) molecules are associated with a set of hydrogen bonds through each amine and imine nitrogen atoms with a Namine...Nimine distance of 3.0264(17)Å.
