(NaLa2)NaPtO6: The first 2H-perovskite related oxide with a rare earth cation on the A-site.
Crystals of (NaLa(2))NaPtO(6) were grown in an acidic ("wet") NaOH flux. (NaLa(2))NaPtO(6) forms in a 2H-perovskite related structure type and contains mixed cation (Na/La) occupancy on the A-site. The crystal was a rhombohedral obverse-reverse twin, and it crystallizes in the space group R3c (hexagonal setting) with lattice parameters of a = 9.5031(2) A and c = 11.4625(5) A. (NaLa(2))NaPtO(6) is the first example of an m = 0, n = 1 (A(3)A'BO(6)) member of the A(3n)+3m)A'(n)B(3m+n)O(9m+6n) family of oxides where either a lanthanide or a sodium cation occupies the A-site.
