“…This is significantly longer than the Te±Te bond lengths in ditellurides (2.680(1) to 2.725(1) A Ê ), the square [Te 4 ] 2+ cation (approx. 2.66 A Ê [20]) or the tetrameric [Te{Cr(CO) 5 }] 4 having a folded Te 4 ring system [21] but close to those found between the triangular faces (3.06±3.15 A Ê ) in Te 6 4+ [22] or in the planar Te 4 rings of the triphenyltelluronium aryltelluro-lates which have recently been published by du Mont et al [23]. They can be interpreted as Te±Te secondary interactions.…”

The reactions between diphenyl ditelluride, (PhTe)2, or di(β‐naphtyl)ditelluride, (β‐naphtylTe)2, with equivalent amounts of iodine have been reinvestigated and the crystal and molecular structures of iodophenyltellurium(II), (PhTeI)4, and diiododi‐(β‐naphtyl)tellurium(IV), (β‐naphtyl)2TeI2, have been determined. The structure of iodophenyltellurium(II) (space group Cc, a = 13.850(5) Å, b = 13.852(3) Å, c = 16.494(6) Å and β = 101.69(2)°, Z = 4) is built up by four PhTeI units which are linked by weak Te–Te interactions with Te–Te distances between 3.152(5) Å and 3.182(4) Å. The angles between the tellurium atoms are approximately 90° giving an almost perfect square. Long range secondary bonds (Te–I: about 4.2 Å) link the tetrameric units to give an infinite two‐dimensional network. Iodo(β‐naphtyl)tellurium(II) is less stable than the phenyl derivative. Solutions of this compound decompose under formation of elemental tellurium and (β‐naphtyl)2TeI2. (β‐Naphtyl)2TeI2 crystallises in the monoclinic space group C 2/c (a = 21.198(6) Å, b = 5.8921(8) Å, c = 16.651(5) Å, β = 114.77(2)°). The tellurium atom is situated on a two‐fold crystallographic axis and Te–I and Te–C bond lengths of 2.899(1) and 2.108(7) Å have been determined.

“…One of the AsF 6-anions in the asymmetric unit is disordered over two equal orientations related by a rotation of ca 45 ° about the F(21)-As(2)--F (22) the OSO angle of 118 (1) ° in the SO2 molecule are comparable with those found for crystalline SO 2 and for SO 2 molecules in other compounds (Burns et al, 1979;Post, Schwartz & Fankuchen, 1952). In (Te6)(Ses)(AsF6)6(SO2) the crystal packing consists of layers of anions and cations parallel to the (101) plane (Fig.…”

“…In attempting to prepare new mixed Te-Se cations by the oxidation of mixtures of tellurium and selenium with AsF 5 in SO 2 as solvent, we have obtained a new dark green crystalline compound which has been shown by X-ray crystallography to contain (Te~+)(Se2+)(AsFz)6(SO2) the two known cations Te~ + and Se i+ (Burns, Gillespie, Luk & Slim, 1979;McMullan, Prince & Corbett, 1971). This is the first time that two different homopolyatomic chalcogen cations have been found in the same crystalline compound.…”

K. CENZUAL, B. CHABOT AND E. PARTHI~ 405 decreases slightly when the fraction of CaCus-type slabs increases. Little variation is observed in the C/a ratio. The situation is different for the members of the ternary series R2+nT3+3nMl+2n. In fact, as mentioned above, the compression of the structure along the c axis is larger for the CeCo3B2-type slabs than for the ternary Laves-type slabs. As expected, the average thickness of the slabs is smaller the higher the fraction of CeCo3B2-type slabs in the structure. The a parameter seems to be determined essentially by the CeCo3B2-type slab and varies little when going from 50 to 100% CeCo3B2-type slabs. As a consequence, C/a decreases when n increases.We are indebted to the D6partement and the exo-endo cyclic Sea 2+ cation. The anion-cation interactions in the structure are discussed.

“…We have found that S7BrMF6 may be prepared essentially quantitatively in liquid sulphur dioxide according to reactions [I] to [5] (17)(18)(19)), in view of the well established (1-3) existence of S71f and the X-ray crystal structure determination of (S7Br)4S4(A~F6)6 (see below) it is reasonable to conclude that S7BrMF6 was formed in all of these reactions. Thus S7BrMF6 can be prepared by a variety of routes.…”

. S7BrMFh (M = As, Sb) were prepared essentially quantitatively by a variety of similar routes to those that led to S71MF6; and in addition, by the reaction of bromine and S71AsFh. (S,Br),S,(AsF,), was prepared essentially quantitatively directly from sulphur, bromine, and arsenic pentafluoride in the appropriate ~a t i o s . Crystals of (S7Br)4S4(AsFh)6 are isostructural with (S71)4S4(A~F6)6r space group P4/11, a = 19.19(3), c = 8.01(1) A. The structure was refined from a low temperature set of data to a final R = 0.12. The salt contains a discrete planar S4" and bromo-cycloheptasulphur ( I +) cations, the latter having a similar geometry, sulphur-sulphur bond distances and an intra-cationic halogen-sulphur contact to that observed in S71+.JACK PASSMORE, GEORGE SUTHERLAND, TOM K. WHIDDEN, PETER S. WHITE et CHI-MING WONG. Can. J. Chem. 63, 1209Chem. 63, (1985.Utilisant diverses methodes semblables B celles qui ont permis de prCparer le S71MF6, on a prCpar6 le S7BrMFh (M = As, Sb) avec un rendement pratiquement quantitatif; on ['a aussi obtenu par la reaction du brome et du S71AsFh. Par reaction du soufre, du brome et du pentafluorure d'arsenic dans des proportions appropries, on a prepare le (S7Br),S4(AsF,), avec un rendement essentiellement quantitatif. . It was of interest to determine whether iodine was unique in its ability to form cations of this sort, therefore, we explored the analogous sulphur-bromine system, and the results are reported in detail below. A preliminary communication briefly mentioned (s7Br).,S4(AsF6) (6). Prior to this work the known binary sulphur-bromine species were S,Br2 (x = 2 to ca. 10) (of which only S2Br2 is stable) (8), SBr3MF6 (M = As, Sb) (9) salts, and the rather unstable NH,SBr (8).
