CRYSTAL STRUCTURE OF SODIUM ETHYLENEDIAMINETETRA-ACETATOANTIMONY (Ⅲ) TRIHYDRATE NaSb(edta)·3H_2O

摘要

C10H18N2O11NaSb, Mr = 487. 0,orthorhombic, space group Pnna,a = 7. 047(1),b= 20. 915(3),c= 11. 152(2) A ,V= 1643. 7 A3,Z = 4,Dm= 1. 97,Dc = 1. 968gcm-3,λ(MoKa) = 0. 71073A ,μ=17. 7cm-1 ,F(000) = 968,final R=0. 040 for 1256 observed reflections. The [Sb(edta)]- ion has a diad symmetry, which differs from the structure of analog [Sb(Hedta)] in [Sb(Hedta)]·2H2O phase.
