| Abstract | Reprint requests to Priv.-Doz. Dr. M. O. Senge. Fax: 0 3 0 -8 3 8 -4 2 4 8 . E-mail: mosenge@chemie.fu-berlin.de A third crystalline modification of dodecaphe-nylporphyrin is described in which the pyrrole ni trogen atoms are hydrogen-bonded to two etha nol molecules. This is the first crystallographic proof for the accessibility of nitrogen atoms in saddle-distorted free base porphyrins for hy drogen bonding. N o such coordination is possible in either planar or ruffled porphyrins. Thus, the possibility exists to utilize conformationally dis torted porphyrins for the binding of neutral m ole cules. | ||
