Near monolayer deposition of palladium phthalocyanine (PdPc) or perylene tetracarboxylic diimide (PTCDI) on the Au(001)- $5\times 28$ reconstructed surface leads to the formation of well ordered molecular assemblies, as observed by means of scanning tunneling microscopy. The PdPc lattice shows locally domains with square or rectangular symmetry having different molecular densities. The underlying gold surface reconstruction remains stable after PdPc deposition, indicating a weak interaction between PdPc and the gold surface. As in the PTCDA case, the PTCDI unit mesh is centered rectangular which is attributed to the formation of H bonds in the lattice.
