چکیده:

the crystal structure are reported for a 4,4 -Azodi(phenylcyanamide) salt ([(n- Bu)4 N)]2 [Azodicyd2-]) in the solid state. The structure was determined by X-raycrystallography. This compound crystallizes in the triclinic space group P1 with the following unit cell parameters: a = 9.759(4) A, b = 1 1.237(4) A, c = 1 1.91 9(4) A, a = 95.54(3)O, 63 = 98.50(3)~, y = 109.39(2)’, Z = 1 and V = 1204.4 A3. The 4,4′- azodi(pheny1cyanamide) dianion, ~ z o d i c ~ di~s -a,p proximately planar, with the cyanamide groups ( -N=C=N) in an anti conformation relative to each other and the azo group ( -N N-) adopting the more thermodynamically stable tuan.5 conformation. The crystal X-ray analysis shows that there are one azo molecule cation. two tetrabutyla~nmonium cations and two water molecules in unit cell. Internolecular 0-H N hydrogen bonds are effective in the stabilization the crystal structure of this compound and to form linear chain structure in packing
