“…21 The properties of several mixed valence ternary chalcogenides have been reported including Eu 5 Zr 3 S 12 which is a Curie paramagnet (m eff = 13.37(1) m B /formula unit) 22 and the polar (Space Group P6 3 ) La 3 Fe 2Àd S 7 , d = 0.042 (6) which orders as an antiferromagnet (T N B 155 K) and exhibits activated conductivity. 23 Three mixed isostructural chalcophosphates APb[PS 4Àx Se x ] (A = K, Rb, Cs; x = 0-4) have been synthesised and exhibit a tendency for the harder S to bond to the alkali metal and Se to bond to the softer Group 14 element. 24…”

“…Neben den gemischtvalenten Alkalimetalloxiden und dem soeben beschriebenen gemischtvalenten Zinnsalz wurde im vergangenen Jahr auch La3Fe2‐dS7 (d ¼ 0,04), das gemischtvalentes Eisen enthält, erstmals umfassend charakterisiert 23. Dabei stehen die Mößbauer‐Spektren der polar in P63 kristallisierenden Verbindung mit der röntgenographisch bestimmten leichten Unterbesetzung der Eisen(II)‐Lagen in Einklang.…”

Iron I 7100The Polar Mixed-Valent Lanthanum Iron(II,III) Sulfide La3Fe2-δS7: Synthesis, Crystal and Electronic Structure, 57 Fe Moessbauer Spectra, Magnetic Susceptibility and Electrical Resistivity. -La3Fe1.958S7 is synthesized from the elements in a LiCl/KCl flux (970 K, 14 d). The compound crystallizes in the hexagonal space group P63 with Z = 2 (Ce6Al10/3S14-type structure; single crystal XRD). The structure contains one-dimensional rods of face-sharing FeS6 octahedra and FeS4 tetrahedra. The Fe-centered polyhedra are linked by La atoms, which are coordinated by [7+1] S atoms in a bicapped trigonal prismatic arrangement. The compound shows an antiferromagnetic transition at about 155 K. The electronic band structure suggests pseudo-one-dimensional metallic conductivity. However, due to the defects on the Fe II positions, La3Fe1.958S7 exhibits an activated conduction behavior. -(MILLS, A. M.; BRAEUNLING, D.; ROSNER, H.; SCHNELLE, W.; SEBASTIAN, C.
