2,6-Bis(acetyloxime)pyridine, 2,6-C5H3N(C2H3NOH)2 (L1), reacts with indium(III) chloride in methanol to give the seven-coordinate complex [InCl3(L1)(MeOH)]. The structurally similar Schiff base ligand 2,6-bis(1-phenyliminoethyl)pyridine (L2), 2,6-C5H3N(C2H3NC6H 5)2, however, forms a six-coordinate indium-(III) complex of the composition [InCl3(L2)]. The In - N bond distances are longer by 0.03-0.12 A in the seven-coordinate compound compared with those in the Schiff base complex. The MeOH ligand in [InCl3(L1)(MeOH)] can be replaced by Cl- or H2O to give the complex anion [InCl4(L1)]- and [InCl3(L1)(OH2)], respectively. The pentagonal-bipyramidal coordination environment of the metal is preserved during these reactions.
