Resumo

Single crystals of MnIn 2 Se 4 have been grown by the chemical vapour phase transport technique using AlCl 3 as the transporting agent. The structure was refined to R = 0.064, R w , = 0.059 for 609 reflections. MnIn 2 Se 4 (R 3̄m, hexagonal axes a = 4.051(1), c = 39.464(2) Å, c/a = 9.74, Z = 3) crystallizes with a nearly close-packed layered structure (sequence of the Se layers ABCA|CABC|BCAB) with M oct (= 0.56 Mn + 0.44 In) in octahedral coordination (M oct ,–Se = 6 × 2.721(1) A) and M tet (= 0.78 In + 0.22 Mn) in tetrahedral coordination (M tet -Se = 1 × 2.527(2) and 3 × 2.593(1) Å). The overall layer sequences is ΑβΒαCyA| Cα AγBβC| BγCβAα B.
