The crystal ofLa(CCl3COO)2 (CH3COO) (phen)(H2O)·DMF]2 belongs to tricliniccrystal system, space group P1with a=1 .2510 (4) nm, b=1.3460(5) nm, c=1.0343 (3)nm, α=102.47(3)°, β=102.34(2)°, γ=113.82 (2)°, μ(MoKa) = 20.47 cm-1, Z= 1, Dc=1. 800 g·cm-3, F (000) =780. 00. The acetate tends to coordinate with the center ion as abridge and trichloroacetate has fourkinds of coordination modes, somany coordination modes were observed in their co-ligand system.展开更多
