Crystal structure of (U,Pu)(Al,Fe)3C3 discovered in a hot particle from Maralinga, and relations to MAX phases. (A) Overview of the layered structure of (U,Pu)(Al,Fe)3C3. (B, C) Coordination of the actinide sites in (U,Pu)(Al,Fe)3C3. (B) and in the topologically similar UAl3C3 (C). The derivative MAX structure of the new phase (A) is compared to two MAX phase sensu stricto structures (Al(Ti)n+1Cin): (D) Ti2AlC (n = 1), Cambridge Crystallographic Data Centre deposition number 1681503); (E) Ti3AlC2 (n = 2), International Crystal Structure Database #93503).
