The compound N, Nʹ-Bis(3-nitrophenylmethylene)cyclohexane-1,2-diamine (α-diimine Shiff base) was synthesized and characterized by MS, IR, NMR 1H and X-ray single crystal analysis. While the cyclohexane-1,2-diamine used for the synthesis of this composite is a racemic cis and trans mixture, we observed by x-ray diffraction for the product N,Nʹ-bis(3-nitrophenylmethylene) cyclohexane-1,2-diamine only the (1R,2R)trans enantiopure. The crystalline network cohesion of this compound is assured by a combination of C-H...O and C-H...N hydrogen bonds. It crystallizes in the monoclinic non-standard I2/a space group
