The crystal structure of [Fe(C36H44N4)(NO3)] has been determined in th
e space group P (1) over bar. The unit cell contains two molecules. Th
e Fe atom is displaced out of the porphyrin plane by 0.50 Angstrom, th
e average Fe-N-p distance is 2.056(1) Angstrom (where N-p is a porphyr
in N atom) and the Fe-O(NO3) bond length is 2.016(3) Angstrom.
