The structure consists of a three-dimensional network of edge-and corner-linked distorted tetrahedral [MO 4 ] entities, with M = Na + and Cd 2+ in a 1:3 ratio sharing a common site set on Wyckoff position 8h in space group I4/m. The large cavities are occupied by A = Rb + in an almost cubic coordination (4/m symmetry), giving rise to one-dimensional chains of face-sharing [RbO 8 ] polyhedra along [001].inorganic papers Acta Cryst.

Zur Kristallchemie der Oxometallate des Cadmiums

“…Vor wenigen Jahren berichteten Kerp und Möller 146 über RbNaCd 3 O 4 . Diese Verbindung entstand als Nebenprodukt einer Reaktion von Rb 2 O, Na 2 CO 3 , V und CdO (6:1:1:1) in Silbertiegeln, die unter Argonatmosphäre in eine Quarzampulle überführt wurden.…”
