Lanthanide phthalocyanine (LnPc2H: Ln =Nd, Tb, Er, Tm, Yb, and Lu) thin films prepared epitaxially on KCl and NaCl crystals have been studied at the molecular level by means of high-resolution electron microscopy. Both tetragonal and orthorhombic structures have been found. It is revealed that the interaction between substrates and molecules, the existence of geometric isomers, the anisotropy of molecular
