 Variables:
   Temperature = N/A

 Prepared By:
   W.E. Acree, Jr.

 Experimental Remarks:
   Authors report formation of a 1:1 pyrene - 2-chloro-1,3,5-trinitrobenzene molecular compound having a melting point of 427.2 K. An eutectic point occurs at x1 = 0.120 and T/K = 348.2. Four incongruently melting pyrene - 2-chloro-1,3,5-trinitrobenzene compounds with 4:3, 2:1, 3:1 and 4:1 stoichoimetries were also reported to exist.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
