C 6I17La12, monoclinic, C12/c1 (no. 15), a = 19.927(1) Å, b = 12.636(1) Å, c = 19.399(1) Å, b = 90.24(1)°, V = 4884.6 Å 3 , Z = 4, R gt(F) = 0.026, wRref(F 2 ) = 0.062, T = 293 K. Source of material Single crystals of La 12I17(C2)3 are extracted from a mixture of LaI 3, La and C (molar ratio 7:8:3) heated under Ar atmosphere in sealed Ta capsules at 900°C for 6 days. La 12I17(C2)3 forms black polyhedra sensitive to moisture.
