The crystal structures of two biphenyl compounds 3‐amino ‐2,4 dicyano ‐ 3',4',5' trimethoxy ‐ 1,3 terphenyl (I) and 3‐amino ‐2,4,dicyano ‐5‐ methyl ‐ 4'‐N,N diethyl amino biphenyl (II) are described here (CCDC NO. : 134369 & 134370). The title compounds C 23 H 15 N 3 O 3 (I) and C 19 H 19 N 4 (II) crystallized in the centrosymmetric triclinic space group P‐1 and non‐centrosymmetric orthorhombic space group Fdd2 respectively. The unit cell parameters are : (I) a = 10.3555(2), b = 10.7103(2), c = 11.0096(0)Å, α = 64.1(0), β = 65.9(0), γ = 89.6(0)° ; Z=2 and (II) a = 23.0364(1), b = 37.2165(1), c = 7.7491(0)Å, α = β = γ = 90.0(0)°; Z=16. The R factors for compound (I) and (II) are 0.053 and 0.064 respectively.
