The title amidine compound, C14H20N2, prepared by a one-pot reaction, is asymmetric as only one N atom has an alkyl substituent. The terminal cyclo-hexyl group connected to the amino N atom is located on the other side of the N-C-N skeleton to the 4-methylbenzene ring and has a chair conformation. The dihedral angle between the phenyl ring and the NCN plane is 47.87 (12)°. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains propagating along the a-axis direction.
通过一锅法反应制备的标题脒化合物C₁₄H₂₀N₂是不对称的,因为只有一个N原子具有烷基取代基。连接到氨基N原子上的末端环己基位于N-C-N骨架与4-甲基苯环的另一侧,具有椅式构象。苯环与NCN平面之间的二面角为47.87 (12)°。在晶体中,分子通过N-H⋯N氢键相连,形成沿a轴方向延伸的链。
