Synthesis and properties of soluble phthalocyaninato-manganese(III) complexes

(Acetato)-1,8,15,22-tetra-n-heptylphthalocyaninatomanganese(III) (C7H15)(4) PcMn(OAc) (+structural isomers) (1) and the octa-n-heptyl-substituted (acet ato)phthalocyaninatomanganese(III) complexes 1,4,8,11,15,18,22,25-(C7H15)(8 ) PcMn(OAc) (2) and 2,3,9,10,16,17,23,24-(C7H15)(8)PcMn(OAc) (3) have been synthesized and characterized by IR and UV-vis spectroscopy and elemental a nalysis. Electrochemical investigations of complexes 1 and 2 (CV, SEC) show similar electrochemical behaviour as the literature known compound (chloro )-2,9,16,23-tetra-tert-butylphthalocyaninatomanganese(III) (t-bu)(4)PcMnCl (+structural isomers) (4).
