The behavior of unsubstituted Zn and Ni metalloporphyrins at the air/water interface in a Langmuir-Blodgett trough has been investigated by examination of compression isotherms, electronic spectroscopy, grazing incidence X-ray diffraction, and X-ray reflectivity. It has been concluded that both metalloporphyrins form bilayers composed of two parallel square arrays of 11.2 Å unit cell length, mutually displaced by about 1/4 of the diagonal, placing the metal atoms of one layer above the pyrrole rings of the other.<br/>
