Nitrophenolate as a building block for lanthanide chains, layers, and clusters.

摘要: Potassium o-nitrophenolate (1) was reacted with various lanthanide trichlorides under different reaction conditions. By using the smaller lanthanides and working rigorous exclusion of air, infinite chains composition [(THF) 4 {K(o-O 2 N-C6H4-O) Ln} ] n (Ln = Y (2a), Er (2b), Lu (2c)) were obtained. Using same conditions but performing crystallization tetradecanuclear clusters H 18 [Ln 14 (μ-η -o-O N-C 6 -O) 8 (η 16 (μ 3 Dy (3a), (3b), Tm (3c), Yb (3d)) isolated. larger center metals such as samarium, europium, terbium layers [[K (o-O 5 Tb] (4) Ln)] Sm (5a), Eu (5b)) In have a closer packing than those in compound 5. The is result increased coordination number metal potassium atoms. contrast, more open structures results channels which are rectangular through layers. All compounds reported including 1 been investigated by single-crystal X-ray diffraction.
