| 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. |
