چکیده
|
A novel sodium alizarin yellow r structure na2(c 13h8n3o5)2(h 2o)2 has been observed by accident when 2-hydroxy-5-((4-nitrophenyl)azo) benzoic acid mono sodium salt (mono sodium salt of alizarin yellow r) was regarded as a ligand. the tetramer was measured by single-crystal xray diffraction,ft-ir spectroscopy and uv/vis spectroscopy. the tetramer crystallizes in triclinic space group p 1 with a = 7.2202(9) å,b = 13.0624(15) å,c = 17.0605(19) å,α = 77.137(2)°,β = 80.922(2)°,γ = 83.354(2)°. v = 1543.56(3) å3,z = 2. there are two crystallographically independent sodium centers in the crystal structure. the local coordination geometry of the two sodium centers [nao6] could be best depicted as slightly distorted octahedrons. the aromantic p-p stacking plays a considerable part in the constitution of 3d network.
