Abstract
The structure and magnetic properties of yttrium diphthalocyanine []⋅ are reported. Phthalocyanine macrocycles are stacked above each other in one direction, with a staggered angle of 45°. One-dimensional organic ferromagnetism is emphasized for the first time, and discussed on the basis of an orbitally degenerate model. A comparison with the behavior of the nonsolvated derivative α- is reported.
