Synthesis and crystal structure of double Np(V) cesium oxalate CsNpO2C2O4 · nH2O
Tóm tắt
An X-ray diffraction study of CsNpO2C2O4 · nH2O was carried out. The structure consists of NpO
2
+
and Cs+ cations, oxalate anions, and water molecules. Dioxo cations are combined by cation-cation interaction into cyclic trimer in which each NpO
2
+
cation act as monodentate ligand. The coordination polyhedron of the Np(V) atom is a pentagonal bipyramid. The similarity of the structures of MNpO2C2O4 · nH2O (M = NH4, Cs) based on cyclic trimers combined by oxalate ions into a three-dimensional framework was confirmed.
