Abstract: The quaternary mixed anion complex of lanthanide [Pr(CH3CH2COO)2(NO3)phen)]2 was synthesized and its crystal structure was determined by Rigaku AFC 7R. The crystal structure belongs to triclinic system with space group P1, a=0.9650(2) nm, b=1.2949(4) nm,c=0.8994(2)nm, α=95.37(3)°,β=111.05(2)°,γ=102.87(2)°,V=1.0037(5) nm3, Dc=1.758 g·cm-3, Z=1, F(000)=528, μ(MoKα)=24.64 cm-1. The final R is 0.024 for 3302 I>3σ(I). The four CH3CH2COO- anions have two coordination modes. Two CH3CH2COO- anions are bidentate-bridging coordination and another two are tridentate-bridging coordination. |
