Abstract: The crystal structure of the title compound, [Nd(H₂O)₉]Cl₃·2C₆H₁₂N₄·4H₂O, is the first neodymium chloride complex with a cage adamanzane without any chloride ion in the lanthanide coordination sphere. The Nd-O distances range from 2.4425  (17) to 2.5635  (18)  Å, and the neodymium ion has the coordination geometry of a capped square antiprism distorted toward a tricapped trigonal prism. The cations, [Nd(H₂O)₉]³⁺, are connected via hydrogen bonds to hexamethylenetetramine molecules, water molecules and chloride ions.
