New form indium(III) phthalocyanine was obtained by the direct reaction of InMg alloy with 1,2-dicyanobenzene at 210 ·C. The InPc₂ is isostructural with SnPc₂; it crystallizes in the orthorhombic system, space group P2₁2₁2₁, with unit cell parameters a = 10.569(3) Å,b = 50.868(11) Å, c = 8.899(2) Å, V= 4784.1 ų, and Z = 4. The crystal structure was refined to R = 0.0322, R_w = 0.0457, and S = 1.11 for 731 refined parameters and 3898 independent reflections having with F > 4s(F). The crystals of InPc₂ contain sandwich-type molecules in which the indium atom is 8-fold coordinated by the isoindole nitrogens of two phthalocyanine rings. The average value of the In-N bond distance is 2.333 Å (2.327(4)-2.346(4) Å). The distance between phthalocyanine planes in this sandwich macromolecule is equal to 2.741(7) Å. The two phthalocyaninato moieties are rotated about 41.2-(4)· with respect to one another. The magnetic susceptibility measurement shows a typical Curie-Weiss behavior. The effective magnetic moment is 1.67 μ_B- The EPR spectrum of InPc₂ exhibits a single strong signal at g = 2.0025. © 1995, American Chemical Society. All rights reserved.
