Abstract

The reaction of one equivalent of In with a molten flux of (Ph₄P)₂Se₅ and P₂Se₅ (1:2), at 250°C gave the (Ph₄P)[In(P₂Se₆)] (I). Stoichiometric elemental synthesis at 750°C produced the Cs₅In(P₂Se₆)₂ (II). The thin, yellow crystals of (I), and the irregular, dark orange crystals of (II), appear to be air-and water-stable. Compound (I) crystallizes in the monoclinic space group C2/c (no. 15) and at 23°C: a = 23.127(7) Å, b = 6.564(1) Å, c = 19.083(3) Å, β = 97.42(2)°, V = 2873(1) Å³, Z = 4, final R/R_w = 4.4/5.2%. Compound (II) crystallizes in the tetragonal space group P4₂/m (no. 84) and at 23°C: a = b = 13.886(1) Å, c = 7.597(2) Å, V = 1464.9(3) Å³, Z = 2, final R/R_w = 3.9/ 5.1%. Compound (I) contains infinite [In(P₂Se₆)]_n^n- with a structure related to that of K₂FeP₂Se₆. Compound (II) contains the discrete [In(P₂Se₆)₂]^5- which can be viewed as a fragment of the [In(P₂Se₆)]_n^n- chain.
