Ad. Gordeev et Gb. Soifer, STRUCTURAL CHARACTERISTICS OF CHLORINE-SUBSTITUTED DIAZADIENES IN THESOLID-STATE FROM (35)NQR DATA, Journal of structural chemistry, 34(2), 1993, pp. 248-251
The quadrupole resonance spectra and the quadrupole spin-lattice relax
ation times of the Cl-35 nuclei are correlated with the molecular stru
ctures of the two chlorine-containing diazadienes CCl3CCl=NCCl=NC6H5 a
nd CCl3CCl=NCCl=NCCl2CCl3. The monotropic polymorphism found in the ca
se of the second crystal is discussed.
