“…1) was first reported nearly fifty years ago (Johnston, 1974), although its structure was published recently (Yamaguchi et al, 2008b). Complexes of the triply deprotonated ligand, (sal) 3 tame, have been reported with transition metals and lanthanides (Sunatsuki et al, 2008;Yamaguchi et al, 2004Yamaguchi et al, , 2008aYokoyama et al, 2010;Kojima, 2000;Kobayashi et al, 2006;Urushigawa et al, 1977), but have received little attention to date with maingroup elements (Katsuta et al, 2012;Kojima et al, 2000). The H 3 (sal) 3 tame ligand has already been used to synthesize potential technetium radiopharmaceuticals (Marmion et al, 1996).…”

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.

Complex formations of copper(II) with some analogous ligands of N,N¢-bis(pyrdin-2-ylmethyl)propane-1,3-diamine and their crystal structures have been reported. 1-4 In a research of the complex formation of CuSO4•5H2O with N,N¢-bis(pyridin-2ylmethyl)propane-1,3-diamine, which was prepared, according to a published method, 5 a green product was accidentally found. It is interesting to identify the unknown green product, because it sometimes leads to finding unexpected compounds. 6,7 Since the green product gave single-crystals in a methanolic solution, the crystal structure was determined. The green product was a copper(II)-2-Py complex ([Cu2(2-Py)2(H2O)(OH)2(SO4)]), where 2-Py is 2-pyrdinecarboxylic acid anhydride. When 0.08 mol of 2-pyridinecarbaldehyde (Wako,
