	abstract = {{The synthesis and characterization of several potentially heptadentate N4O3 Schiff bases and amine phenols, as well as a series of their mononuclear and dinuclear complexes with indium and the lanthanides are reported. Schiff bases containing imidazolidine rings were the products of the known condensation reaction of triethylenetetramine with 3 equiv of 5-substituted salicylaldehydes to form H(3)api (5-H-substituent), H(3)Clapi (5-Cl-substituent), or H(3)Brapi (5-Br-substituent); KBH4 reduction of these Schiff bases gave the appropriate isomeric N4O3 amine phenols H-3(1,2,4-btt) and H-3(1,1,4,-btt), as well as an acetone adduct, H-3(1,2,4-ahi). The Schiff bases reacted with 1 equiv of a lanthanide (Ln(3+)) nitrate to produce mononuclear nine-coordinated [Ln(H(3)Xapi)-(NO3)(3)] complex wherein the ligand adopts a tridentate capping coordination mode, whereas the amine phenols formed mononuclear seven-coordinate complexes with the lanthanides and indium; homodinuclear complexes [LnL]2 were also obtained with the Schiff bases. The X-ray structures of the Schiff bases H(3)api and H(3)Clapi, the mononuclear amine phenol complexes Yb(1,2,4-btt) . 0.5CH(3)OH and In(1,1,4-btt), and the homodinuclear Schiff base complex [La(Brapi)](2) . 2CHCl(3) have been determined. Crystals of H(3)api (C27H30N4O3) are monoclinic, space group P2(1)/a},

The heptadentate ligands are KBH4 reduction products of the Schiff bases derived from the condensation reactions of tris(2-aminoethyl)amine with 3 equiv of one of salicylaldebyde (tris(((2-hydroxybenzyl)amino)ethyl)amine (H3L1)), 5-chlorosalicylaldehyde (tris(((2-hydroxy-5-chlorobenzyl)amino)ethyl)amine (H3L2)), and 5-bromosalicylaldehyde (tris(((2-hydroxy-5-bromobenzyl)amino)ethyl)amine (H3L3)). The reaction of an amine phenol with 1 equiv of a lanthanide (Ln) nitrate produces the mononuclear complex [Ln(H3L)(NO3)3]; homodinuclear complexes [Ln(L)]2 were obtained from the reaction of lanthanide salts with the respective ligand in the presence of a base (hydroxide or acetate). The X-ray structure of [Gd(L1)]2.2CHCl3 (H3L1 = tris(((2-hydroxybenzyl)amino)ethyl)amine) has been determined; it is the first structurally characterized example of an [Ln(L)]2 complex, a homodinuclear eight-coordinate lanthanide complex [Ln(L)]2 with heptadentate ligands only. The complex crystallizes as a chloroform solvate in the triclinic space group P1BAR with a = 12.002 (2) angstrom},
