“…The overall coordination geometry and deprotonation features of the two ligands are identical with that found in the (Chang et al 1993;Salta & Zubieta 1997). In {M 2 O 4 [(OCH 2 ) 3 CCH 3 ] 2 } 2-(M = Mo, W) all three arms of the tripod are deprotonated (Liu et al 1990;Delmont et al 2000). Single deprotonation occurs in {Cr 2 Cl 4 ([(OCH 2 )HOCH 2 ) 2 (CEt] 2 } (Talbot-Eeckelaers et al 2006).…”

“…Transition metal complexes that arise from the tris-hydroxymethyl ethane ligand CH 3 C(CH 2 OH) 3 are not widely reported in the literature. Structures identified by X-ray crystallography include the triply deprotonated form in cluster compounds of molybdenum and tungsten (Liu et al 1990;Delmont et al 2000) and dimeric and cluster compounds of chromium (Talbot-Eeckelaers et al 2006), the doubly deprotonated form in dimeric vanadium-oxo complexes (Chang et al 1993;Salta & Zubieta 1997) and the fully protonated form in monomeric yttrium complexes (Chen et al 1997). For titanium only µ3-O and µ2-O coordination modes have been identified (Boyle et al 1995).…”

The title complex, [Ti2Cl4{CH3C(CH2O)2(CH2OH)}2], lies across a centre of symmetry with a diethyl ether solvent molecule hydrogen bonded to the –CH2OH groups on either side of it. The TiIV atom is coordinated in a distorted octahedral geometry by a tripodal ligand and two terminal chloride atoms. There are three coordination modes for the tripodal ligand distinguishable on the basis of their very different Ti—O bond lengths. For the terminal alkoxo ligand, the Ti—O distance is 1.760 (1) Å, the asymmetric bridge system has Ti—O bond lengths of 1.911 (1) and 2.048 (1) Å. The Ti—O bond length for the alcohol O atom is the longest at 2.148 (1) Å.

The heteroatom should be introduced with a labile ligand, and we chose the acetylacetonate (acac) or acetate (OAc) complexes of Mn III , Fe III , Ni II , and Zn II .…”

Hydrothermal reactions of molybdenum(III) oxide with isoquinoline under different pH values lead to two new octamolybdate-based polyoxometalates (POMs), namely, (C 9 H 7 NH) 4 (C 9 H 7 N) 2 [Mo 8 O 26 ] (I) and (C 9 H 7 NH) 4 [(Mo 8 O 26 )(C 9 H 7 N) 2 ]·2(H 2 O) (II), and their structures were determined by single-crystal X-ray diffraction analysis. The two compounds represent the first report of [Mo 8 O 26 ] 4-based POMs associated with isoquinoline ligand. Compound (I) has 3D supramolecular framework based on hydrogen bonds between [β-Mo 8 O 26 ] 4-fragment and protonated isoquinoline (C 9 H 7 NH) + . Compound (II) contains [(γ-Mo 8 O 26 )(C 9 H 7 N) 2 ] 4-units constructed by [γ-Mo 8 O 26 ] 4-units and isoquinoline through Mo-N bonds.
