{[SmCl(en)4][In2Te4]}n: an indium telluride with a one-dimensional sinusoidal chain.
The title compound, catena-poly[[chloridotetrakis(ethylenediamine-kappa(2)N,N')samarium(III)] [indium(III)-di-mu-tellurido-indium(III)-di-mu-tellurido]], {[SmCl(C(2)H(8)N(2))(4)][In(2)Te(4)]}(n), consists of a one-dimensional sinusoidal {[InTe(2)](-)}(n) anionic chain and [SmCl(en)(4)](2+) cations (en is ethylenediamine). The only other previously reported lanthanide analogue, viz. [LaCl(en)(4)][In(2)Te(4)], contains more usual linear one-dimensional {[InTe(2)](-)}(n) anion chains [Chen, Li, Chen & Proserpio (1998). Inorg. Chim. Acta, 273, 255-258]. The one-dimensional polymeric {[InTe(2)](-)}(n) chain is built of InTe(4) tetrahedra sharing opposite edges. The Sm(III) ion in the [SmCl(en)(4)](2+) cation is nine-coordinated by eight N atoms from four bidentate en molecules and by one chloride ion to form a monocapped square-antiprismatic geometry. The presence or absence of N-H...Cl hydrogen bonding is shown to affect the conformation of the anion.
