Synthesis, molecular and electronic structure of an incomplete cuboidal Re3S4 cluster with an unusual quadruplet ground state

“…4 Unlike numerous examples of molybdenum and tungsten M 3 Q 4 clusters, their Re analogues remain much less investigated. 5 In 1990 the first synthesis of a family of Re(V) trinuclear cluster chalcogenides of formula [Re 3 Q 7 X 6 ]X (Q = S, Se; X = Cl, Br) was reported.6 In these systems with six CSE and three metalmetal bonds, the rhenium atoms define an equilateral triangle with a capping chalcogen and three bridging dichalcogenides. The cluster core in [Re 3 Q 7 X 6 ]X shares structural and electronic features with the M 3 (m 3 -Q)(m-Q 2 ) 3 unit found in the polymeric {M 3 Q 7 X 4/2 X 2 } N (M = Mo, W) phases, widely used as starting materials for the preparation of molybdenum and tungsten M 3 Q 4 cuboidal complexes upon treatment with phosphanes.…”

Synthesis of layered platelets by self-assembly of rhenium-based clusters directed by long-chain amines

“…2b). Interestingly, these granules consist of clusters of atoms with a variable morphology: most of them present a diamond (rhombus) shape, which resemble the clusters observed in ReQ 2 (Q = S, Se), [41][42][43] while other structures, such as triangles or polyhedrons are also observed (Fig. 2b-d and Supplementary Fig.…”

“…The ability of rhenium to form chalcohalide compounds which contains rhenium-rhenium single or multiple bonds has led to the report of a variety of structures, which includes triangular-shaped clusters of the type [Re 3 [45][46][47][48] In the rhenium chalcohalide clusters, the rhenium-rhenium distances are in the range of 2.60 to 3.40 Å, while the rhenium-selenium distances are around 2.5 Å. 41,44,47,49 In the clusters reported in this work, the rhenium-rhenium The main features of the XRD pattern, a series of peaks of decreasing intensity observed in the region between 6 and 18 Å, are due to the harmonics of the 00l reflection resulting from the spacing between the clusters layers. The distance between layers was calculated from these peaks, yielding a value of 30.3 Å, similar to the step distances measured by AFM and also in good agreement with the interlayer spacing found in other materials which contain long-chain amines between layers.…”

Design of Cyano‐Bridged Coordination Polymers Based on Tetrahedral Rhenium Cluster Cyanide Complexes and 3d Transition Metals

“…Significant progress in the developing chemistry of Re 4 cluster compounds was achieved after synthesis of the chalcogenide-halide clusters [Re 4 Q 4 (TeX 2 ) 4 X 8 ] (Q = S, Se, Te; X = Cl; [5] Q = Te, X = Br [6] ). The tellurium-containing complex [Re 4 Te 4 (TeCl 2 ) 4 Cl 8 ] was prepared by the reaction of ReCl 5 with elemental tellurium at 350°C.…”
