The sexadentate ligand 1,1,1-tris[(salicylideneamino)methyl]ethane has been reported numerous times in its triply deprotonated form coordinated to transition metals and lanthanides, yet it has been rarely employed with main-group elements, including in substituted forms. Its structures with gallium and indium are reported as solvates, namely, ({[(2,2-bis{[(2-oxidobenzylidene)amino-κ2 N,O]methyl}propyl)imino]methyl}phenololato-κ2 N,O)gallium(III) pyridine monosolvate, [Ga(C26H24N3O3)]·C5H5N, the acetonitrile 0.75-solvate, [Ga(C26H24N3O3)]·0.75C2H3N, and ({[(2,2-bis{[(2-oxidobenzylidene)amino-κ2 N,O]methyl}propyl)imino]methyl}phenololato-κ2 N,O)indium(III) dichloromethane monosolvate, [In(C26H24N3O3)]·CH2Cl2. All three metal complexes are pseudo-octahedral and each structure contains multiple weak C—H...O and/or C—H...N intermolecular hydrogen-bonding interactions. The syntheses and additional characterization in the forms of melting points, high-resolution mass spectra, infra-red (IR) spectra, and 1H and 13C NMR spectra are also reported.

“…By using this complex-as-ligand strategy, we were able to prepare face-sharing di-, tri-and tetranuclear complexes. Various 3d±3d and 3d±4f ferromagnetic polynuclear complexes have been prepared with this Ni ligand complex (Ohta et al, 2001;Yamaguchi et al, 2004;Kobayashi et al, 2006). The title Zn II compound, (II), has also been used as a ligand complex.…”

In the crystal structures of both title compounds, [1,3-bis(2-hydroxybenzylidene)-2-methyl-2-(2-oxidobenzylideneaminomethyl)propane-1,3-diamine]nickel(II) [2-(2-hydroxybenzylideneaminomethyl)-2-methyl-1,3-bis(2-oxidobenzylidene)propane-1,3-diamine]nickel(II) chloride methanol disolvate, [Ni(C(26)H(25.5)N(3)O(3))](2)Cl x 2 CH(4)O, and [1,3-bis(2-hydroxybenzylidene)-2-methyl-2-(2-oxidobenzylideneaminomethyl)propane-1,3-diamine]zinc(II) perchlorate [2-(2-hydroxybenzylideneaminomethyl)-2-methyl-1,3-bis(2-oxidobenzylidene)propane-1,3-diamine]zinc(II) methanol trisolvate, [Zn(C(26)H(25)N(3)O(3))]ClO(4) x [Zn(C(26)H(26)N(3)O(3))] x 3 CH(4)O, the 3d metal ion is in an approximately octahedral environment composed of three facially coordinated imine N atoms and three phenol O atoms. The two mononuclear units are linked by three phenol-phenolate O-H...O hydrogen bonds to form a dimeric structure. In the Ni compound, the asymmetric unit consists of one mononuclear unit, one-half of a chloride anion and a methanol solvent molecule. In the O-H...O hydrogen bonds, two H atoms are located near the centre of O...O and one H atom is disordered over two positions. The Ni(II) compound is thus formulated as [Ni(H(1.5)L)](2)Cl x 2 CH(3)OH [H(3)L is 1,3-bis(2-hydroxybenzylidene)-2-(2-hydroxybenzylideneaminomethyl)-2-methylpropane-1,3-diamine]. In the analogous Zn(II) compound, the asymmetric unit consists of two crystallographically independent mononuclear units, one perchlorate anion and three methanol solvent molecules. The mode of hydrogen bonding connecting the two mononuclear units is slightly different, and the formula can be written as [Zn(H(2)L)]ClO(4) x [Zn(HL)] x 3 CH(3)OH. In both compounds, each mononuclear unit is chiral with either a Delta or a Lambda configuration because of the screw coordination arrangement of the achiral tripodal ligand around the 3d metal ion. In the dimeric structure, molecules with Delta-Delta and Lambda-Lambda pairs co-exist in the crystal structure to form a racemic crystal. A notable difference is observed between the M-O(phenol) and M-O(phenolate) bond lengths, the former being longer than the latter. In addition, as the ionic radius of the metal ion decreases, the M-O and M-N bond distances decrease.

“…Octahedrally coordinated polynuclear Ni(II) complexes are an interesting class of compound because of a variety of molecular structures and magnetic interactions [5][6][7][8][9][10][11][12]. With phenol-based tetradentate chelating Schiff base ligands, Ni(II) produces several trinuclear complexes with an additional acetate bridging in the l-1,3 mode.…”

“…Therefore, the development of methods for the preparation of polynuclear complexes of targeted topology and a predefined number of metal atoms is an essential step for the investigation of this phenomenon. Self-assembly of first-row transition metals with suitable bridging ligands has proved to be a very powerful approach for well-defined arrangements of metal ions [3,4].Octahedrally coordinated polynuclear Ni(II) complexes are an interesting class of compound because of a variety of molecular structures and magnetic interactions [5][6][7][8][9][10][11][12].

“…With phenol-based tetradentate chelating Schiff base ligands, Ni(II) produces several trinuclear complexes with an additional acetate bridging in the l-1,3 mode. It is worth noting that variable temperature magnetic studies have been performed [6][7][8][9][10][11][12] only in a few of these complexes and antiferromagnetic coupling was observed. However, a tridentate reduced Schiff base (2-methyl-2-(2-methyl-benzylamino)-propan-1-ol) is found to produce a ferromagnetically coupled trinuclear Ni(II) complex [13].…”
