N2 - In this manuscript are reported the synthesis and characterization of the first complexes of indium incorporating the acen and salen classes of ligands. This includes the compounds of formula LInMe (where L = acen (1) (N,N'-ethylenebis(2-hydroxy-α-methylbenzylidenimine)), salen (2) (N,N'-ethylenebis(2-hydroxybenzylideneimine)), salophen (3) (N,N'-(1,2-phenylene)bis(2-hydroxybenzylidenimine)), salomphen (4) (N,N'-(4,5-dimethyl-1,2-phenylene)bis(2-hydroxybenzylidenimine)). Attempts to prepare the derivatives, [In(R)(salpen)] (salpen = N,N'-propylenebis(2-hydroxybenzylidenimine), R = Me, Et) led to the formation of the bimetallic complexes, [(InMe2)2(salpen)] (5) and [In(Et2)2(salpen)] (6). Dissolution of 5 and 6 in MeOH causes the formation of three unusual products. They are the ligand bridged compounds [{In(μ-OMe)(μ-salpen)}2] (7), [(In(salpen)}2(μ-salpen)] (8) and the methoxy-only bridged complex, [{In(salpen)(μ-OMe)}2] (9). Compounds 7-9 are the first structurally characterized indium-salen complexes. For purposes of comparison, the structure of [{Al(salen)(μ-OMe)}2] (10) will also be described.
