ChemInform Abstract: A Model for Trivalent Actinides in Media Containing High Carbonate Concentrations — Structural Characterization of the Lanthanide Tetracarbonate [Co(NH₃)₆] [Na(μ‐H₂O)(H₂O)₄]₂ [Ho(CO₃)₄]×4H₂O.

Abstract

structure structure (solids and liquids) D 2000 01 -006 A Model for Trivalent Actinides in Media Containing High Carbonate Concentrations -Structural Characterization of the Lanthanide Tetracarbonate [Co(NH 3crystallizes in the monoclinic space group P2/n with Z = 2. The structure contains the [Ho(CO 3 ) 4 ] 5− anion with four bidentate carbonate units, the [Co(NH 3 ) 6 ] 3+ cation, and two Na + cations which are bound to ten water molecules in an edge-sharing bioctahedral geometry. The IR and Raman spectra of the compound are given and confirm the bidentate character of the carbonate ligands.-(BOND, DEBORAH L.; CLARK, DAVID L; DONOHOE, ROBERT J.; GORDON, JOHN C.; GORDON, PAMELA L.; KOEGH, D.
