Hydrothermal Synthesis, Crystal Structure and Properties of a Lanthanum(Ⅲ) Complex Based on a N,O-Donor Ligand
摘要:
A novel metal-organic complex [La(o-NCP)3]n (o-HNCP=2-(2-carboxyphenyl)imidazo(4,5-f)(1,10)-phenanthroline) has been hydrothermally synthesized and characterized by elemental analysis, infrared analysis and X-ray single-crystal diffraction. The complex crystallizes in triclinic, space group P1 with a=9.898(2), b=16.193(3), c=16.909(3) Å, α=67.68(3), β=80.85(3), γ=78.78(3)°, V=2448.2(8) Å3, Z=2, Mr=1156.9, Dc=1.569 g/cm3, μ=0.71073 Å, F(000)=1164, GOOF=1.065, the final R=0.051 and wR=0.123 for 8539 observed reflections with I>2σ(I). The complex exhibits a one-dimensional double chain structure. The adjacent chains are further connected by N-H…N hydrogen bonds which help to form a two-dimensional supramolecular architecture. Furthermore, the complex exhibits excellent thermal stability and luminescent property.
