The anionic tetra-kis-complex of lanthanum(III) NMeLa with the CAPh-ligand dimethyl (2,2,2-tri-chloro-acet-yl)phospho-ramidate (H), namely, tetra-methyl-ammonium tetra-kis-{2,2,2-tri-chloro-1-[(di-meth-oxy-phosphor-yl)imino]-ethano-lato}lanthanum(III), (CHN)[La(CHClNOP)], has been synthesized, crystallized and structurally characterized by X-ray diffraction. The lanthanide ion is surrounded by four anionic, bis-chelating CAPh ligands forming the complex anion with a coordination number of eight for La and NMe as the counter-ion. The coordination polyhedron of the La ion was inter-preted as a triangular dodeca-hedron.
镧(III)的阴离子四聚体配合物NMeLa与CAPh配体二甲基(2,2,2-三氯乙酰基)磷酰胺酯(H),即四甲基铵四聚体-{2,2,2-三氯-1-[(二甲氧基磷酰基)亚氨基]-乙醇酸根}镧(III),(CHN)[La(CHClNOP)],已通过X射线衍射法合成、结晶并进行了结构表征。镧系离子被四个阴离子双螯合CAPh配体包围,形成了配位阴离子,La的配位数为8,NMe作为抗衡离子。La离子的配位多面体被解释为三角十二面体。
