Abstract:

The crystal is monoclinic P21a. At room temperature a20.07, b7.56, c5.88 A, beta96.52, Z2, formula C22O4H20. The structure was determined from a three-dimensional Patterson synthesis, and refined by least-squares procedures. Two sets of intensity data were used independently. One was collected at room temperature with the use of a scintillation counter the other was recorded on Weissenberg photographs at - 130C, and estimated visually. The 14 peripheral atoms of the pyrene nucleus are approximately coplanar, and appear to form an aromatic system. Author
