N2  - Powder X-ray diffraction, e.p.r, and magnetic susceptibility studies on copper 4,4',4'',4'''-tetrasulfonated phthalocyanine, Cu(tspc), and &#945;-copper phthalocyanine, &#945;Cu(pc), are reported. Cu(tspc) was found, by analogy with the previously reported structures of the &#945;, &#946; and &#947; forms of Cu(pc), to have a triclinic unit cell of dimensions a 26.9, b 3.8, c 25.6 Å, &#945; 89.9, &#946; 90.0 and &#947; 95.5º. The e.p.r. and magnetic susceptibility data for both Cu(tspc) and &#945;Cu(pc) suggest the presence of exchange interaction. The magnetic susceptibility data are best explained by using an S = ½ Heisenberg chain model with J -0.84 and -0.71 cm-1 respectively.
