 Title    Fixation o f Neutral M olecules in the Binding Cavity of Nonplanar Porphyrins -A Third Dodeca- phenylporphyrin Modification with NH -Solvent Hydrogen Bonding  
 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.
