Adjustable networks : The tetracyanamidosilicates A(RE)[Si(CN 2 ) 4 ] are formed by solid‐state metathesis reactions and contain the novel [Si(CN 2 ) 4 ] 4− ion. Depending on the alkali metal ion (A=K or Rb), orthorhombic or tetragonal network structures are formed in which the rare‐earth (RE) ions have differently distorted trigonal‐dodecahedral environments. The crystal structure of RbLa[Si(CN 2 ) 4 ] is shown (Rb yellow, La red, Si gray, C brown, N blue).
