1 Source of material

All materials were purchased from commercial suppliers and used without further purification. Tris(2-hydroxyethyl)amine (7.46 mg, 0.05 mmol) and Y(NO3)3·6H2O (19.15 mg, 0.05 mmol) in 10 mL of methanol were sealed in a Teflon-lined stainless steel autoclave. The reaction mixture was heated at 120 °C for 24 h and gradually cooled to room temperature. White block-shaped crystals were obtained with a yield of 38 % based on tris(2-hydroxyethyl)amine.

2 Experimental details

The structure was solved and refined with the SHELX programs. Hydrogen atoms were located in geometrically calculated positions. Their Uiso values were set to 1.2Ueq or 1.5Ueq of the parent atoms.

3 Comment

Design and synthesis of lanthanide complexes with novel structures and properties have attracted increasing attention in the fields of molecular magnets, catalysts, ion recognition, or luminescent materials. 4 , 5 , 6 , 7 As is well known, suitable organic ligands play an important role in the construction of metal complexes, in which the specific ligand fields can effectively regulate the molecular physico-chemical properties. In our previous work, some paramagnetic lanthanide complexes based on tris(2-hydroxyethyl)amine ligand have been synthesized and studied. 8 This multidentate chelating ligand can effectively separate central metal ions in high-symmetry coordination geometry. As a continual work, a multinuclear diamagnetic yttrium(III) complex based on tris(2-hydroxyethyl)amine were further prepared and structurally determined. This complex crystallizes in the monoclinic system with P21/n. The asymmetric unit is one half of the tetranuclear complex (see the figure). Y1(III) ion is eight-coordinated by seven oxygen atoms (O1, O1A, O2, O3, O4, O7, and O8) and one nitrogen atom (N1), while Y2(III) ion is nine-coordinated by eight oxygen atoms (O2, O4, O5, O6, O10, O11, O13, and O14) and one nitrogen atom (N2). The Y–N bond and Y–O bond lengths range from 2.569(3) to 2.979(3) Å, and 2.204(2) to 2.589(3) Å, respectively. Central yttrium(III) ions are connected by two μ2-O units from tris(2-hydroxyethyl)amine ligands to form a zigzag-type Y4 core with intramolecular yttrium(III) ions distance of 3.6798(6) Å.
