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.
(NaLa₂)NaPtO₆晶体是在酸性（“湿”）NaOH助熔剂中生长的。(NaLa₂)NaPtO₆形成于一种与2H-钙钛矿相关的结构类型，且在A位上含有混合阳离子（Na/La）占据情况。该晶体为菱面体正-反孪晶，它属于空间群R3c（六方晶系），晶格参数为a = 9.5031(2) Å和c = 11.4625(5) Å。(NaLa₂)NaPtO₆是A(3n + 3m)A'(n)B(3m + n)O(9m + 6n)氧化物家族中m = 0、n = 1（A₃A'BO₆）成员的首个例子，其中镧系元素或钠离子占据A位。
