2,3,9,10,16,17,23,24-Octakis(phenoxy)phthalocyaninato manganese complex MnCl[Pc(OPh)8] (1) was prepared and spectroscopically and electrochemically characterized. For the comparative reason, 2,3,9,10,16,17,23,24-octakis(octyloxy) phthalocyaninato manganese analogue MnCl[Pc(OC8H17)8] (2) was also prepared and comparatively studied. The molecular structure of 1 with a central chloridized trivalent manganese ion has been clearly determined by single-crystal X-ray diffraction analysis. The third order nonlinear optical properties of 1 and 2 in toluene solution were studied using Z-scan technique, giving effective imaginary third order molecular hyperpolarizability of 1.44 × 10−11 and 2.27 × 10−11 esu, respectively, indicating the potential application of the phthalocyaninato manganese complexes in the optical limiting.
